Claybar

I overheard some guys talking about claybar to clean scuffs off of their boat, anyone know what this is?

Don't mean to sound like a smartass but it's a bar of clay. shaped like a bar of soap sort of. you can buy them at pretty much any automotive store. They are great for really putting a shine in a paint job but I have never heard of them being used on fiberglass personally.

Really, I would think that would leave a residue on whatever it was rubbed on.

Hey 21, I've seen them used on a black boat, and they do an excellent job, but they require more work than any other form of wax I've ever seen.

Good luck.
