They also sell a UV protector for it also. I do not use it as an adhesive. I used my regular old wood glue on my canoes. I dont think you will need to clear coat this stuff. Its kind of milky when you first lay it on, but after about 2 hrs it is as clear as glass. Plus there are no brush streaks, as it levels out great. I put on 3 coats, and sanded between each coat, as my customers wanted a glass like finnish. I have used this stuff for about every outdoor project i have built, and it still looks great. It is not cheap, but is the only thing i use.
