Rust is difficult to kill, nevertheless Eastwood has the ammunition to assist cull the beast. Lock and cargo, gearheads, it’s time to eradicate some oxides.

Whereas oxidation is a course of that the majority metals are topic to (sure, even aluminum and low-cost stainless), none are as vulnerable to the detrimental results like iron-based metals. If left untouched, rust will render metal again to the earth, and it occurs sooner than it’s possible you’ll notice. The setting across the automobile performs a big position in rust formation. If in case you have ever been to Michigan, you perceive simply how briskly steel can rust away. On a latest journey to Detroit, we noticed a 4-year previous car with fully-rusted rocker panels. Within the southern states that takes 15-20 years of standard use. The distinction is the salt publicity; salt provides an electrochemical response, which accelerates the method. The important thing to stopping rust is to seal it off from oxygen. Pure, dry oxygen doesn’t rust steel, however the mixture of moisture and oxygen is a lethal combine for metal. Including a barrier is one of the simplest ways to guard the steel. As soon as that barrier is compromised, then the oxidation begins nearly instantly.

It’s important to eliminate the rust so as to cease it. Even a single tiny spec of rust can result in extra, even underneath shiny paint. There are a number of strategies of rust removing: media blasting, chemical compounds, and the basic cut-and-replace. We’re going to look into every methodology and share some suggestions and tips alongside the best way utilizing some Eastwood merchandise.

Rust all the time has a method of rearing its ugly head, and in case you simply band-aid over it, it should worsen. The cab nook on this ’81 Chevy truck was not doing so good. The one answer when the rust is that this unhealthy is to chop out. Patch panels like this one can be found for hottest physique kinds. Don’t let the rust get this unhealthy, repair it earlier than you must take drastic measures.

CUT AND REPLACE

As soon as the steel has holes in it, you simply must chunk the bullet and substitute it. Whether or not it’s a pinhole or all the quarter panel, the method is similar; reduce out the encircling steel and weld in some recent steel. The trick right here is to take away sufficient materials to eliminate the weak rusted steel. The place there’s a gap, there’s much more skinny steel able to crumble. One trick we use is a steel decide. Faucet the encircling steel with decide and a hammer. If the decide goes by way of the steel, its junk, if it dents very easy, it might be getting skinny, contemplate going additional. After getting eliminated the offending steel, that you must prep the remainder of the steel to kill any present rust and defend it for the longer term. That’s the place the following two strategies are available.

Tech Tip – earlier than welding, spray the joints and any areas behind the weld with Eastwood Weld-thru coating to guard the recent welds from rust.

MEDIA BLASTING

A private favourite, when accomplished effectively, rust has no protection in opposition to the abrasive energy of high-pressure blasting. Nonetheless media blasting comes with an awesome many caveats that that you must find out about earlier than making an attempt by yourself. The primary one is security. All the time put on a respirator or fresh-air hood when doing any media blasting. Defend your pores and skin by carrying lengthy sleeves, lengthy pants and gloves. A faceshield is one of the simplest ways to guard your eyes from ricochets.

Sometimes called merely “sandblasting”, media blasting lately shouldn’t be accomplished with sand. Sand releases free silica when it’s crushed or damaged, which is what occurs when the crystals hit the components underneath excessive stress. Free silica will get into your lungs and causes a situation referred to as silicosis. By no means use sand in something apart from an enclosed blast cupboard. For automotive use, there are a number of way more appropriate media for blasting; these are baking sodawalnut shellaluminum oxide, and crushed glass.

Soda blasting is a delicate course of that’s secure for issues like chrome, glass, wooden and even engine components. Right here a Ford 302 is being soda blasted with an Eastwood Twin-Media blaster. Baking soda can also be best for fiberglass automobiles, akin to this ’67 Corvette. Utilizing the mistaken media on fiberglass will destroy it in seconds.

Baking soda is the least aggressive of all blast media. Soda blasting is usually reserved for delicate components and the place that you must take away paint whereas not damaging any of the encircling areas, akin to painted parts of chrome trim. Soda is not going to hurt rubber, glass, chrome, however it additionally gained’t contact rust. Soda is mild; it may be used to blast absolutely assembled engines with out worry of damaging the bearings or gaskets. Baking soda is softer than bearing materials; it should crush into powder and be absorbed into the oil, and eliminated by the filter. Baking soda is the one blast methodology that needs to be used on fiberglass , all the pieces else it just too aggressive. Something blasted with baking soda have to be neutralized with both Eastwood Quick Etch or vinegar and water (10:1 water to vinegar combine is enough). If this neutralizing step is just not taken, the paint gained’t stick. Quick Etch has the added bonus of defending the steel from flash rusting. One other good thing about soda blasting is the cleanup. Different media varieties must be swept up, whereas soda merely washes away with water, doing no hurt the setting. When blasting greasy components, the soda truly encases the grease, permitting for a straightforward sweep up of the gunk, it gained’t smear on the bottom.

Tech Tip – Whereas all baking soda merchandise are chemically the identical, blasting soda is completely different from the stuff you purchase on the grocery retailer.  Blasting soda particles are bigger, extra uniform in dimension, and there further elements that support within the movement and cleanup. In addition to, it will take loads of these little bins to replenish a blast pot!

Walnut Shell is a good various to the dearer baking soda. It really works very effectively for inner engine components, blocks and aluminum. Grease doesn’t stand an opportunity in opposition to walnut shell blasting. Walnut shell is extra aggressive than soda, however much less aggressive than crushed glass. It’s reusable and secure for the setting. The most important downside of walnut shell is that may be very dusty. Walnut shell blasting gained’t take away rust, however it does take away the dimensions related to rust. That is nice for utilizing merchandise like Rust Encapsulator and Rust Convertor.

Here’s a distinctive situation- an empty engine bay with useable wiring and elements, however it must be stripped and painted. Walnut shell is ideal for this. Utilizing a industrial blaster, the engine bay was blasted, the walnut shell gained’t have an effect on the glass, rubber or chrome, however it does wonders for eradicating the grease and paint. That is the tip end result. Discover that the walnut shell left the floor rust and didn’t profile (depart sand scratches) the steel. We used some Eastwood PRE prep spray to scrub all the are earlier than refinishing the engine bay.
The rusty spots have been handled with Eastwood rust converter after which topped with Rust Encapsulator. Subsequent, we blended up some Eastwood Epoxy primer
and loaded up a Concours spray gun with a 1.Four tip set.
Primed and prepared for paint. We notice the windshield is just not taped up, it’s popping out anyway. We used Eastwood Scorching Rod Black single-stage paint to provide the engine bay a killer look. This all took a few day.

Crushed glass is the popular methodology of stripping paint and rust off steel. Crushed glass is available in completely different sizes, however the optimum sift dimension is a #4, or 40-80 mesh. That is sufficiently small to get into the pits and enormous sufficient to get the job accomplished shortly. Crushed glass has low mud, might be recycled and it’s low-cost.  Crushed glass is constructed from recycled glass and it doesn’t launch free silica, making it secure for the setting. Rust is shortly stripped with crushed glass, leaving solely clear white steel. #Four glass depart a 80-120-grit profile on the floor, which is ideal for spraying paint and primer.

Extra aggressive blasting is required when coping with severe rust like this S-10 body. Right here we’ve got a industrial blaster utilizing crushed glass to eradicate the rust. The result’s clear, white steel that’s prepared for extra Eastwood primer and paint.

Aluminum Oxide is one other glorious media for autobody rust removing. It’s reusable far past what any of the opposite media varieties are able to and is low mud. It isn’t low-cost; so blasting a whole car with Aluminum oxide is an costly proposition, particularly in case you don’t have a method to recall it. Aluminun oxide in a blast cupboard may be very economical nevertheless, because it lasts a very long time and not using a loss in effectiveness.

CHEMICAL REMOVAL OR CONVERSION

Blasting makes a multitude and requires particular tools, however chemical compounds simply take time. These merchandise from Eastwood will get the job accomplished, and are nice for small components.

Chemical Rust Elimination has been round nearly so long as rust itself, however the strategies have modified enormously in the previous few years. Most chemical rust removers contain soaking the components in a liquid that eats the rust, leaving clear steel on the floor. There are various kinds of chemical rust removers, a lot of that are extremely acidic and might harm delicate components. Eastwood provides a number of options for secure rust removing.

Eastwood Rust Dissolver is an acid-free chemical tub that removes rust whereas not attacking the steel itself. Flippantly rusted components might be cleaned in a number of hours, whereas closely rusted components can take as much as 48. After soaking, a fast rinse with recent water will get the components are prepared for primer or powder coating. The cool factor about this product is that it’s reusable, so you may get a good quantity of mileage from one buy. The components have to be dipped within the answer and left there till the method is accomplished, so the bigger the half, the extra you want. For physique panels and actually huge components, Rust Dissolver is accessible in a gel, which makes use of the identical chemical formulation as the usual Rust Dissolver, however formulate as a clinging gel. Merely brush it on, let it sit for 24 hours after which clear it off with Eastwood PRE prep cleaner.

As a check, we used a bit of scrap steel that was scaly and rusty to see Rust Dissolver works. The liquid doesn’t have an effect on the plastic tub. The half have to be absolutely submerged for this to work. After a few hours, you’ll be able to see bubbles from the chemical course of consuming the rust. After 24 hours, the half was largely rust free. This may be nice for small components, or massive physique panels utilizing the gel method.

Tech Tip – Take away any unfastened, scaly rust BEFORE utilizing Eastwood Rust Dissovler. It will velocity up the method and reduces the quantity of labor the chemical compounds must do. Slightly elbow grease goes a good distance.

Eastwood Rust Convertor doesn’t take away rust, relatively it converts it utilizing a proprietary method to cease the oxidation course of and defend it from future rusting. It’s actually a rust killer in a rattle can. It may be used on any floor and is appropriate with most topcoats.

You should take away any unfastened scale earlier than spraying the convertor on the half; it must be clear, identical to any paint-type product. Grease, grime and different contaminants will hinder the convertor’s capacity to seal the rust.

Right here is an A-arm for a Corvette. The highest aspect had been blasted, however the underside obtained missed. Regardless that
it gained’t ever be seen, we have to kill the rust.
We taped up half of the half and sprayed one aspect to see what sort of distinction Eastwood Rust Convertor makes. You’ll be able to see the black floor the place it was sprayed. The convertor goes on clear, and thru chemical processes, kills the rust and turns into a primer layer.

Among the best-selling merchandise that Eastwood has to supply is Rust Encapsulator. Much like Rust convertor, Rust Encapsulator seals the rust, converts it, and supplies a wonderful primer for high coating. We use these items prefer it grows on timber.
