Since I mostly build scale I don't do much with monokote but the decals sticking wouldn't be an issue but I'm assuming you're refering to the shrinking qualities of the covering material and would the krylon stand up to a heat gun to get rid of a few wrinkles. I would probably try the clear lusterkote over the decals once they are in place. It would probably be best to take some 000 or 0000 steel wool to the area before applying the decal which would aid in the clear to adhere better. I think the lusterkote is probably tougher around glow fuels as well. Jim
