This is a great sealant. As strange as it sounds, it smells kinda good in a weird "what's that chemical smell" way. It is a white liquid that dries on clear; this is helpful so you can see where you've already put the sealant on. Without its color it'd be pretty hard to see where clear liquid has been placed. And it does what it is supposed to. I'm trying to figure if I only need one coat or maybe two coats like the bottle suggests as a possibility.
