White Residue

Here is a picture of one of the decals I fixed on to my first serious plane and it’s poor as you may see:

Does anyone know what the problem is? I primed the model with Halfords grey primer then sprayed with Mr.Color 365 gross seablue then sprayed with future/klear. All other decals seemed ok. What did I do wrong?

To me it looks like more than one issue. First, there looks to be silvering under the decal (air trapped under the decal film) and second, a common occurance when a decal solvent reacts to future that has not quite cured (I usually wait at least 24hrs after clear coating). The second problem can be cured around the edges of the decal with another coat of future, but for what’s underneath, you can try poking small holes in the silvered areas and applying a decal setting solution (not a solvent, as this could further cloud the future under the decal), which I would try before you spray on the second clear gloss coat.

Thanks for the advice, but I forgot to mention that I did use Mr.Mark softener when applying the decals is there a safer product to use when trying to fix this problem? Thanks.

I agree, it looks like something reacted with the overcoat, in this case Future. I know it SAYS the stuff dries in 20 minutes or so, but I’d wait at least overnight before applying anything wet to the surface. You don’t say what brand of decals they are, but MicroSol is pretty benign to most brands of decals.

Agreed. I thought at first glance of the title of the thread that you were speaking of the milky white glue residue we often found on cheap decals in the 80s and early 90s, which had to be removed after the decal was dried. This looks like a reaction. I believe Mr. Mark softener is alcohol based, and alcohol reacts with Future (boy dont I know that!!) especially when traped under the decal film where it cannot evaporate.

Micro sol, and WARM water will take care of most of your decal delimmas.

OK, Thanks folks. Time to buy some MicroSol.

I believe that Micro-sol is also alcohol-based. If that is the case, then I would be hesitant to put it under markings that have a lot of clear carrier film, as it would be tough to get at should the same problem arise. Micro-set might be better underneath, and the -sol up top, where it would be easier to fix with simply another coat of Future. Of course that could all be academic if the Future has had sufficient time to cure.
