If I get married again I'm using 5200 to keep us together forever.
Its 5200. There is nothing like 5200. I've tried a dozen times to use something cheaper, faster, easier tube, etc. and I always go back to my main squeeze of good old 5200. Not even 5200 Fast Cure comes close to the slow, sticky goo that won't come off your skin and ruins any piece of clothing it touches. Old school 5200 teaches patience as it takes days if not weeks to fully cure but what you get is a bond only slow, original 5200 provides. If 5200 won't bond it then you did not clean and prep your surfaces, or the universe doesn't want it to happen with anything. I love you 5200... We are together forever. Literally...

3M Sealant is fabulous
3M Sealant whether brown, mahogany, or white is absolutely the best for any sealing job. I use white fast cure on my RV windows and RV roof. Compared to even the best silicone caulk or RV roof sealants, the 3M is far better. It is definitely worth the extra cost. It is able to be painted too. Try it, you will see what I mean.

5200 is the best sealant for the Marine Industry if you're looking for strength and longevity for joints above and below waterline. However, if large areas of the joint will be exposed to UV, try selecting an alternative 3M product, such as 3M 4000 UV.
