The BEST thing for boating since water!
I have no idea what this stuff is, but it freakin' works. We've used it on the front of the camper, you know, where all the bugs in the world go "SPLAT". A few coats of BTS and the front of the camper, and the entire camper, is much easier to clean. It's so easy to clean now that the bugs almost slide off with just pressure from the hose. No joke. BTS is some amazing stuff. Oh yeah, it works pretty good on you boat, too.
