Arg great info guys but painting seems like such a daunting task now,,,tho it was bad enough before ;)
I know my wags need a coat before too long, its still pretty rust free, but things like inside the holes in the cross-floor-box-sections (body cross members? whatev you call them?) have some rust that will be hard to get at without blasting.
It seems there are as many ways to do it right as to do it wrong!

D is this the link you were talking about? Ive always liked the idea of this method...if only for the fact that it would be dirt cheap and you can take your time with it...like painting your car over a few months might give you no reason to take shortcuts and only needing to prep one area at a time. But if it were that simple maybe there might be more people doing it :/

So edp youre saying just use no converters whatsoever after ensuring all the rust has been cut out? To neutralise a converter with water seems like its just risking more rust in some areas. then what...is it always nessecary to etch-prime on bare metal?
