Eastwood Fast Etch Rust Remover 1 Gallon

I used this on some 56 Chevy sedan doors. I've used similar products in the past, and this works at least as well if not better. I had some more stubborn spots on a couple of the nooks in jamb areas, but I just let it work for a few minutes and reapplied more etching solution and it gradually just went away. I used dark maroon scotchbrite pads from a local paint store for application. Just cut a couple chunks off, fold them over once to allow the solution to soak in a little and get to work. You'll know when it's time to get a new one, the pads will eventually disintegrate… I allowed it to sit per the directions and used some disposable blue shop rags with copious amounts of acetone to clean it all off…only do the areas you're prepared to do as the etching solution can evaporate and you'd have to reapply. When alls done, It leaves a hazy dullish gray finish on bare sanded steel. If you don't get all the residue off, it'll feel almost tacky to the touch. Now, if you're not familiar with these types of chemicals, you need to Read the directions and the warnings-this stuff is acidic, so you have to wear some splash and skin protection. It also outgasses some noxious fumes like hydrogen sulfide (rotten eggs) during the conversion process, so ensure you have more than adequate ventilation or you'll likely wind up with a headache. Oh-if you're working on a large area or many panels, just buy the gallon and pick up a couple spray bottles from a local hardware store, it makes application a lot easier.
