Weld seams showing through new paint job

[Rick Giles]

I was curious if it had anything to do with the actual weld. And maybe not the bondo/primer application or the product used. I've seen this on some cars. And the reason I'm asking is I have a 69 Camaro with the original quarters with rust issues in the usual areas over the rear tires. But it has an awesome fit around the trunk lid. I really hate to mess that up. Not to mention all the factory joints and welds. Just don't want to have the same problems with the quarter patches later with weld lines coming back.
