I think they are similair in price. 5200 is known as an adhesive sealant - it is mainly a sealant that has adhesive qualities. As an adhesive it would fall way short of the strength of true structural adhesive. Sheer strength would only be measured in the hundreds instead thousands of PSI. It's best quality is that it's very flexible and will withstand the repeated abuse that a boat can dish out and still hold. If you don't need a full 10 oz cartridge, they do sell it in a smaller tube. I think I've seen it a Wal-Mart.
