Appears model paints do well without a sealer. Attempt is to preserve as much laser cut detail as possible. Stains work well, model paint is thin/provides the color needed. A dull, satin, or gloss coat applied with an air brush a final two steps. Gloss before decals, Satin or dull after decals as a finish. IMO Mike CT.
