Review: 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...
Review: Good but expensive. Worth it though. - Expensive but very good quality.
