I think 3M will have just about any product you would need in the way of adhesives, sealants, etc. There may be some other good brands, but I have such good results with 3M that is the first stop for me.

I used 3M 5200 when I did mine.

Its a polyurethane compound and does a great job sealing up leake in joints.

Actually, 3M 5200 is a urethane compound (according to everything I have ever seen). Not sure why they leave out the "poly". But if you go that route be aware of a couple of things:
1. they make a fast cure and a slow cure version
2. they make it in black, and white
3. it is recommended for through the hull fittings on boats; it might look like caulk, but it is a lot more money because it is a much better product

good luck

Thanks for posting the details Sam.

It's a much better product than what they use at the factory. When I converted my C5 Coupe to a FRC widebody I used it to redo the rear tub as well as the roof.

A lot of the C5 fixed roof coupes develop leaks on the top deck and sides as GM uses a very stiff glue at the factory, however after a period of time the seams where they glued them crack due to stress and flex in the body, which creates all the leaks that everyone seems to have after they get some miles on their vettes.

I'm not sure what they do with C7's.
