Seam sealer - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I posted this question in the Paint and Body forum 2 days ago. It got 11 looks, 0 replys so I'm trying it here because I know someone here has an answer.......

My '67 C-10 cab is finally down to bare metal. Finished all patch welding (all floors, rockers, kicks, front pillers and corners, whew!) and sprayed on a see thru coat of 2K epoxy to limit rust until the plastic work is done.

I've asked a few 'experts' about when I should replace the seam sealer (especially in the drip rails):
over bare metal?
over the epoxy?
over the 2K urethane primer filler I hope to spray next week? Got too many answers, not sure if any of them are right.

Can someone who's BTDT offer advice?

You will have the best results if you primer coat over the body caulking. For the question of application over bare metal vs. a primed surface. I prefer a primed surface. It's easier to apply, as well as see what you are doing. Once you're satisfied with your results coat it well with primer paying attention to any fisheyes that might occur. Any imperfections could possibly show in your finish paint. Good question I hope this helps.

starting at the bare metal......

1.) etching primer
2.) seam sealer
3.) sealing/ hi build epoxy primer
4. ) top coat

hope this helps.......
