White 3M Marine 5200 Adhesive/Sealant 10 fluid ounce cartridge

Expensive, does what it says. I had a leak in a glass roof and used this. It took a couple of days to dry but the leak has completely stopped.

Delivered on time, well packaged. Used on the boat transom to fill in transducer screw holes. It's easy to use. It does take a week to fully cure but works perfectly. I recommend for anyone working on a boat. Use a caulk tube plug to seal and save unused product.

Purchased this product to attempt to seal a challenging flashing issue which has three different material in an awkward transition. I removed all the material from the previous two attempts to waterproof the area, leaving a larger than previous opening to work this material into. After cleaning and prepping the surfaces, I began to applying this 3M product. It is thick, but not problematic to dispense - possibly other reviewers were dispensing through a smaller orifice than me - I used the full tube opening without a tip. The product is exceptionally easy to manipulate and smooth out - almost putty like. Unlike other products like silicone and polyurethane, it didn't stick much to my applicator and thus stayed were I wanted it (without sag) and also smoothed out easily. Bottom line is it adhered to all three materials, filled the voids perfectly, looks great, and the leak is no more! I highly, highly recommend this product - it's amazing!

Este pegamento es una bestia! Lo Utilice para unas botas y quedó incluso mejor que con la suela original, lo unico es que es dificil resellar

Great stuff, holds strong and cleans up great with thinners. Stays soft for 2 days full cure after 7 so if you need it quick use the fast cure, just as good.
