Xtra Cut is Bio-Kleen's more aggressive step for fiberglass that's seen serious sun damage, chalking, or oxidation. It combines a heavier-cut compound with a polish in one product, so you can cut through dulled gelcoat and bring color back without switching between two separate products.
It's formulated to remove light scratches and oxidation while leaving behind UVA/UVB protection rated to 250°F, and it contains no silicone, so it won't interfere with future paint or clear coat work. It's safe for use on OEM paint, clear coat, single-stage paint, and gelcoat with either wool or foam pads.
Best used as a restoration step on heavily oxidized surfaces before following up with a dedicated wax or sealant for maintenance shine.
