A year ago, my dad had my truck frame sandblasted, but it rained on the frame as we towed it back from the blaster. Go figure. Since then, I've been doing extensive suspension work on the frame. It still isn't primered, so needless to say, it has some surface rust. I've kept the rust at bay on the large, flat sections with a body grinder and 80 grit pads, but I can't reach in the little nooks and crannies or behind the boxing plates. I read about electrolysis using a tub, a sacrificial electrode, laundry soda, and a battery charger. Has anyone tried this method? Would it be safe to try on a full frame -- say, a 1950 pickup frame? And how long would the frame need to be submerged? Normally, I would sandblast it again, but I still can't blast behind the boxing plates and I'd rather save the money for a new spray gun... or college books.
I would imagine as long as I don't do anything stupid (i.e. go swimming with the frame), this method is completely safe, but I've never read of anyone doing a large object like this before. Is the electrode required prohibitively large? The larger the object being electrolisized, the larger the electrode required, but the frame is relatively clean, except for some surface rust.
I assume I would have to neutralize the soda afterward because it is very basic, so what is the recommended method for nuetralization before painting (I'll be using SPI epoxy)? Dawn/ Ajax soap and water?
Thanks,
Chris
