If anyone is looking for a good spray gloss overcoat, this is what I use....especially over waterslide decals after they have been applied to the rocket. I sometimes use it over self-adhesive decals too. It seems compatible with every brand paint I use....KRYLON, RUSTOLEUM,etc. The only negative is that it has an odor while drying and is relatively expensive in that it only comes in a 3oz. can for about $4.00. I seem to only get about 2 rockets per can....but the finish is very nice. I have had humid paint problems and this spray will bring out a nice glossy finish. Even works well over some silver or metalflake finishes. It is TESTOR MODEL MASTER LACQUER OVERCOAT GLOSS finish. I just used it over my RENEGADE metallic paint.
