Wow Thanks!
That is a good question ... my main priorities before the snow flies are the 3rd brake light/washer nozzle area and the bottoms of my doors (pass. rear and drv. front both rusting)... The rest is just trying to make those repairs fit

Oh I forgot the few dozen new gravel and stone scratches thanks to my wheel adapters :waytogo:
I still am not sure what I'm going to use to prep. I have already tried grinding all of the visible rust away (inside of door), used a rust converter and then bedliner type coating. It rusted through within a year, now the paint is bubbling on the outside as well.
I saw this liquid once... hardware store?... I think it was meant for getting rust off tools.... I was thinking of making something like a wall paper tray and soaking the bottoms of the doors in the stuff after I re-grind it all again. :shrug:
