I used this adhesive to install foam on my Factory 5 car kit. It was easy to work with and has a long cure time to allow plenty of time to apply.

It is a little watery so be cautious. it may drip. And because it takes a while to dry. But once it's dry it has a very good adhesion. It is very waterproof.I would recommend this silicone.

Not just for marine use.
I bought this to do some transom repairs. It did not fail to do what I needed. I have used it to seal building penetrations (electrical & plumbing). All have remained weather tight. It has never failed (as long as I follow the directions) to provide positive results. The only complaint I have is I don't always need a full tube. Smaller packaging (1 oz.) would be great.

Worked as advertised!
Worked as advertised. Was applied in cooler weather (mid 50's F), so took 5-6 days to cure and get hard as rock.
