I really don't think so.

Be cautious with chemically stripping any automotive part that the metal overlaps, such as a door. It is nearly impossible to get all of the stripping agent out from between the seams. You may think you did a good job of washing the seams but the part will leach stripper even after what you thought was a thorough job.

A friend put together a beautiful 64 Dodge Dart in which the doors had been chemically stripped. The acid leached out onto the new paint corroding it, making a mess of the fresh paint job. He went as far as taking the doors off and tried to thoroughlly clean out the seams sealed and repainted with no luck. It got better but they still leached the stripper. He ended up putting on two doors that were blasted with plastic beads.

As a rule I will chemically strip parts with no seams and bead blast the parts that do.

Just my .02 cents.

When stripping with acid the acid must be neturalized with a high ph (alkaline )then rinse with a iron phosphate that will hepl neturalize the alkaline. Wait with about a week before priming to allow all moisture to dry.Then use a 2 part self etching primer.

Bruce,
How can you dip fiberglass?

Dave's process does not use an alkaline process. I asked him about the weld seams, he said his chemicals use themselves up, so there is no residual etching once he completes the process. He has been doing this for many years, and hasn't had any complaints.
