Is that the factory seam area, common problem area. Sounds like a good idea to me just to patch it up.
I doubt you can get to the place you need from the inside. I have seen many cars with rust on the A pillars83imp said:I am starting on the body of my '83 Imperial and I am a little disappointed with one area. The rust in the quarters didn't bother me as that is normal for a 20yo+ car. However, up toward the top of the passenger-side A-pillar between the windsheild trim and the door window trim, there is a small hole rusted in the pillar. This seems like an odd place to rust.
Can you get to the backside of the pillar if you remove the a-pillar trim on the inside?
I was thinking of "fixing" this with the POR-15 system and patching the hole with their Restogrip filler. The hole is probably 3/32" diameter. Its pretty small and doesn't appear to have spread much past the actual hole, but it stuck me as odd that the car would even rust up there. Any other suggestions? I really don't have the time or resources to weld in a different pillar and the car isn't worth it either.
