bought some "new" doors for me 46 gmc. they have been outside for years, all the paint is off, and they have surface rust all over. they are good solid doors with no holes, dents, etc. only the surface rust.
I've never started a repair on this type of rust.
What's the best way to proceed to get these to bare metal for a nice flat paint job?
thanks all for your help.

A good guy on a sand blaster could also clean them up real nice and not warp your doors.

One thing that I found when removing the skins was that there was rust remaning inside the crimped areas. That is just a fact of life as there is no way of getting in there. | | | | | Joined: Jan 2002 Posts: 38 New Guy | | New Guy Joined: Jan 2002 Posts: 38 | thanks for the tips, I will search for a stripper in my area, although I don't think there are any. LaCrosse WI area, anyone know of any?
any other ideas for a low budget project?
i was thinking a light sanding, then phosphoric acid treatment, then sand again, primer, sand again? will that work?
