Paint and body question

[sdstang]

I'm including a pic of a seam that I see the paint crack in a lot in finished paint jobs and don't know what steps I can take to prevent it. Just stick regular seam seal in it. Is the 2k a better option? Somebody suggested to trying to V it out some.

Sem structural adhesive or seam sealer dual mix https://www.semproducts.com/brand/13-dual-mixtm ..I would call tech and ask for their recommendation for that application .You could also weld the seam then file cut a line.

Thanks for the input Scott!

The paint on this joint sometimes cracks due to the expansion and contraction of the spot welded joint. The roof is spot welded to the quarter panels and A pillars but is sealed with lead at the factory..

IMHO, you could weld the joint and cut a fake seam, but if you are off just slightly with the grinder, could cut into the thin sheet metal, missing the weld and cause yourself more work. I would lead it in and just scrape a seam over the joint with a file which would not cut into the sheet metal.. It's what I do..
