I have had my car for (gulp) 20 years now. I completed the mechanical rebuild (motor, trans, rear end) 15 years back. And I de-rusted it (lower qtrs, lower fenders, trunk pan, core support) 5 years back. I have been tackling each step during the winters, and then putting it back together to keep driving it. Now it is time to break it down and repaint! I am currently taking the car down to bare metal, as the one repaint it had was very thin and had some cracking through the paint. The car has never been the the prettiest, but.....I have only found two small thin areas of any bondo, and no rust repairs other than what I have done. I feel I am very lucky having this as my first re-paint. I will attach a few pictures to frame the project, and then jump in with my questions. In the booth Bondo driver side, passenger had it in about the same spot Passenger door jamb
First question, I have rust holes on each side of the rear window... about where the factory lead is. I am not sure if this can be welded, does the lead go into the window channel? I have scraped/sanded the rest of the rear window channel, and welded the (1) other hole I found. I am wondering if the rust in the channel should be treated with POR15, or will the epoxy I plan to shoot the entire car with be enough to treat it? Also... seam sealer, should it be done before or after the epoxy primer? Fixed rust hole, bottom passenger
Por is good stuff, but for that area here is my suggestion,..blast it with a little "speed blaster" they are cheap and perfect for this kind of stuff Blast it Epoxy prime it Buy a tube of 3M 8115 epoxy Fill the hole and sand smooth The repair will outlast you and the next owner Its non intrusive and is fast and easy, that's about max size hole I would span with it but it will do fine
That body seam could use some epoxy primer. then day later . Or when you primer car. use 2 part epoxy in the seam after you put maskin tape on both sides. swipe epoxy with finger pushing in down in. Then wipe with shop wipes with thinner on towel. lightly. 2 part automotive epoxy is like $60. to $80. tube. But well worth the money. Do not put mud in that seam. That’s A really nice Buick
