Works as advertised
By Woody from Tennessee River

I used it to smooth seams I was caulking on a rebuilt transom. It worked as advertised. It made smoothing out the bead easier than water or paint thinner.

Bottom Line Yes, I would recommend to a friend

Easy to use, nice product
By QB from Lake Michigan

Verified Purchase

Good stuff. By the time of the year when I am caulking; my fingers are usually shot from sanding and the typically harsh boat commissioning hand work. This stuff allows for easy clean up, wipe your fingers. It works with regular below the waterline caulk by BoatLife (good stuff) and also works with the ugly stuff like 5200. I use it for all gluing and stuff like that with success. It also taste good. Just kidding, I didnt taste it.

Bottom Line Yes, I would recommend to a friend
