How do I finish / paint cut foam?

Question

Two paths:

**Quick**: light sand with 220-grit paper to even out the melt surface, then prime with FOAM-SAFE primer (water-based latex, or Plasti-Dip, or Plastikote Foam Coat). Then any acrylic/spray paint on top.

**Production**: laminate the cut foam with fibreglass + epoxy for a hard durable shell, fill imperfections with auto body filler, sand, prime, paint. This is how RC wings and surfboards get their durable surface.

DO NOT use solvent-based primers/paints directly on EPS — they'll eat the foam. Always test on a scrap piece first.
