Well, foam stain stripes can be a pain, especially on an EPS blank. Gotta tape off and do the stripes, then tape off the stripes and seal the rest of the blank. A pain. Other than that, I personally would do old school resin stripes on the hotcoat and under a gloss. Got Cobalt?
I would also recommend that you paint them on the hotcoat, but putting epoxy over the paint may give you some problems. I would sand the hotcoat to 80 grit, airbrush the stripes with a quality acrylic like Novacolor, and then use a poly glosscoat. Poly will flake off epoxy in a short time unless it’s sanded rough. If you want more durability than just a gloss over the paint, cover the group of stripes with clear 4 oz using poly after painting, hotcoat and fair in the cloth. Then poly gloss.
