Review on 3M Marine Sealant 5200 - Black, 3 Ounces - Permanent Bonding and Sealing for Boats and Marine Applications by David Batte

My aluminum fishing boat has not been out of service for a long time. In the test there were drops everywhere. I used this material on all sections with painters tape to keep it nice and the edges clean. I had enough for everything I did, which is the whole boat. It took 7 days to stop being sticky but when we put it in the water. NO LEAKS AT ALL. Great item and looks great. It can get messy, which is why you need masking tape. Peel off the tape after attaching it with your gloved finger and it will look great. You can work with it for a long time.
