Minor Engine Bay Rust Treatment -Prepaint
Electrolysis is for hair removal. Lol!
youtube it, knocks all the rust clean off. I have done it several times.
the best muscle car restorers use it if they can get new or good used replacement metal. private metal treatment companies have tanks large enough to dip the whole car tilting it on the way in to remove all pockets of air in proprietary caustic solution. removes all rust, paint, body filler and seam sealer. there is one guy in Florida that goes after the seam sealer between spot welded sections with homemade knives and hooks to remove the trapped sealer. he even circles the areas that he cant get it out of.
the only sad thing about it is alot of cars come out looking like Swiss cheese, it removes rust in areas where you thought there was no rust.
it also harms no good metal unlike acid dipping or using stuff like vinegar or molasses.
