Works great
Used this in a recent solar panel install on a van and so far seems to work great. Been through one very significant rainfall about a week after install and everything seems to be sealed tight. Along with sealing our install, it also seems to have a very strong adhesion as even when things are unscrewed, still holding on strong. Made the mistake of forgetting a caulk gun...don't do that, not too easy to apply without it.

The best on the market
I use this product on the desk of my yacht with excellent performance. Also use it on the exterior of my older RV while the old sealant is dry, cracking and not holding the trim in place. The UV additive and consistency makes it the best buy. I have given up on 3M 5200/4200.

Ask about product date before purchase.
Purchase or be advised this product has the best before date. I was unaware of this when I purchased it and found out the best before date is only good for 7 months after I received it.
