Welcome to Troton

If the scratches are not deep, then we can renew the scratched side by polishing with Sea-Line polishing pastes. Above the waterline, when the scratches are not deep, the surface can be repaired with a DRY FAST gel coat filler. Deep scratches should be filled with epoxy filler (selected depending on the requirements of the scratched surface), painted with a primer and then painted with topcoat.

We recommend to always sand the surface between applying two different products to ensure uniform surface roughness and adhesion of subsequent layers. The sanded surface should also be cleaned and degreased.

Yes, you can mix Sea-Line polyurethane paints. The only difference are the pigments of polyurethane paints that determine the color of the paint. But remember to keep the right proportions of base, hardener and thinner.
