There's some rust inside my (4)doors. Its not horrible, but I figure I might as we'll take care of it before I finally paint them. With all the layers of paint on the outside, there's going to be some cost to removing it all. I found a place in Eugene that will dip them to remove paint, remove rust, and treat for rust...$80 per door which doesn't seem too bad...except I have to get them to Eugene and back.
Anyone have any experience with dipping for rust?
Is it better to just blast them inside instead? (Steve? You're a lot closer now that I think about it. What about powder coating just the inside?
Anyone know of someplace closer than Eugene that does dipping?
Appreciate all advice!

The place in Eugene is the only one up here. Most of them closed because of the EPA regulations.
As far a powdering them that is what I did. Strip everything out of the doors, and I do mean everything. Blast them clean and then I powder the entire door,inside and out with my epoxy primer. You do your body work and paint right over that. It works very well! Let me know if I can help you out.
The dip shop charges $80 per door? That's $320 plus travel time. I think my cost of powder and oven time might only be about $200 to do all 4.

That sounds like a plan...
Will the body shop worry that it's not their primer?
Maybe I should do the wheels hood and trunk lid that way too.

I can powder coat the hood and trunk but cannot blast them they warp way to easy. I can blast around the braces but not the unsupported metal.
It's new to most shops but it work better than there traditional sprayed on epoxy primer. Wheels piece of cake.

When you powder coat the hood or trunk lid, what happens to the old paint inside the channels that you can't get in to remove?

Usually nothing. You can powder right over paint but then the powder becomes a removable product just like the paint. When I got done sanding my hood there was little or no paint left anywhere. I can powder into more places than paint ever thought about going. Powder is electrostatic and will stick anywhere there is conductivity. So in my opinion this primer powder coat is a way far better base than any paint. That is why I did my whole car in it, I was able to powder under the dash, in between the outer quarter panels and the inner panels. I am pretty confident that my car will NEVER rust again. [thumb]

Very cool. I would have thought any paint left inside the channels would flake off in the baking.
What about the fenders? Can you blast those?
Also, do you have a link or a spec sheet with info about the primer for me to read about?

Fenders are no problem. The manufacturer or the powder is Cardinal paints, there is a link to them off my web site. Doghousepowdercoating.com.
Not sure how much info they have on it. I believe the code on it it gr233 pr something like that.

No. That is a zinc based product. You need to look for epoxy based. I'm not working today or I'd give you the code number. I thought it was GR-533
