  • clear waterproof rubberish coating
Model: 35.3 OZ
This is what it says, it dries clear. I appreciate that it came with a little brush and a little smoothing tool, but since you're supposed to apply it in multiple coats maybe more than one brush would have been a nice touch? Anywho, time will tell how well it holds up.
