I always put Future over decals before I shoot a solvent based clearcoat. Future is water based so it will not attack decals or paint. Future can cause some types of white paint to yellow, but I have never had a problem with Future over Testors white. Clearcoats use a mixture of solvents that might include ketone, acetone, toluene or xylene. If you use an enamel paint you have to be careful if you put a laquer clearcoat on top of it. Once I hit one side of a body with no problem, but when I did the other side the paint was damaged. Krylon Crystal Clear seems to be less likely to cause problems, but it does not resist chipping as well as products intended for automotive use. Lately I have started to coat everything with Future before I shoot the clearcoat. I have cars that have had Future on them for many years and I hace never had a problem with it turning yellow. I pour some Future into a small screw cap bottle and work from that. I never pour unused Future back into the original container.
