I have a wooden case that came with my 6" Mod 29. Its in great shape on the outside, but the inside is just a black piece of molded, hard plastic of some sort with a one inch thick piece of foam in the lid. The foam has lost its blue color and the little lid for the tool compartment has also faded to almost black with a bit of Royal blue showing here and there. Can I color the foam somehow? Caan flocking material be glued to the hard plastic ( I don't think the hard plastic ever had any color on it, its the one where the revolver faces to the right).?
