3M 36103 Perfect-IT Gelcoat Heavy Cutting Compound - Fiberglass Oxidation Remover

Is your boat's gelcoat looking chalky and faded?

Bring that shine back to life with 3M's Perfect-IT Heavy Cutting Compound.

This is the stuff the pros use.

It's a heavy-duty compound specifically designed to cut through heavy oxidation on fiberglass and gelcoat surfaces.

You just brush it on (it's a brush-on application), work it in with a buffer, and watch the old, dead layer come off, revealing the fresh color underneath.

It's made by 3M, so you know it's quality.

This is the 36103 formula, the one you want for serious restoration jobs.

Your boat, RV, or fiberglass project will look showroom new again.

Fair warning for our California friends: this does have the Prop 65 warning.

But for everyone else, it's the go-to for making oxidized gelcoat shine like glass again.
