Over the years I have used several brands of marine sealents and bonding agents. This product hands down is the most reliable and all around useful product I have ever used. I found a great way to get the full use out of a large tube of 5200. Simply take it out of the caulking gun after its original use. Wrap kitchen use plastic wrap around the tip and stick it in the freezer. Its as simple as that. I have had one tube last up to 3 days after multiple uses.

I have used 5200 to bond and seal thry haul fittings and had good reuslts. Last spring I used it to re-caulk my Mahoghany toe rail to the fibreglass. Uncovered the boat this Spring and the 5200 was all cracked, exposing the Seam. 5200 sticks to both wood and fibreglass but elasticity properties are poor. Used Boatlife caulk on part of the job and the seam is still sealed, no cracks.
