The best sealant to seal bait boats up with
This is by far the best sealant to seal up bait boat hulls. It dries quick, easy to work with, smooths great with the help of soapy water, its not too thick so you dont have to struggle pumping it out with the gun. Nice rich dark black semi-gloss colour, blend in well with black gloss abs. Good value for money as 1 tube will do most boats that require sealing (microcat/technicat).

Did what I hoped
Used this to seal the walls of a concrete panel garage to the concrete base. Was easy to apply and filled the gaps. Quite hard to push into the gaps and then smooth as its very sticky, needs a wet finger to help a bit As proof of use - in the very heavy rain in the UK late September I had standing water outside the garage but the inside was dry so a success - would use again

Top notch
Dow, always good and never had a problem with any of their sealers and silicones. I won’t buy any other brand.
