frosting dullcote

Im beginning to think god doesn't want me to finish this model.... Im almost done with my Jagdpanzer. However the skirts are giving me trouble. Twice now ive painted the base coat, waited a few days for it to dry, painted the camo, waited another two days, then covered with dulcote. These are with Tamiya acrylics by the way. Both times seemingly random areas develope a white "frosting" i guess you would call it where that spot looks extremely faded. Other part of the skirts are unaffected. The only thing i can come up with is i didnt wait long enough for the underlying layers to dry but then wouldnt it have occured more evenly over the entire part? Im at a loss. Any help would be greatly appreciated.

I had that problem happen once when I applied dulcote outdoors here in the steamroom belt. I applied it on the carport on a summer day in SC when the humidity was over 80%.

A second coat applied indoors in air conditioning solved the problem.

Good luck.

did you have to sand the first off or did the second settle it down.

After the first time, I reapplied the base coat and camo. I covered it up essentially.

I had this happen on a Hasegawa 1/48 F-16. I had good luck getting rid of the frosting by letting the dullcote dry, then soaking the model with isopropyl rubbing alcohol using a spray bottle. I had to do this several times, with the frosting diminishing each time until it was finally all gone. Scott Wilson

I just applied the 2nd coat. I did wait several days to make sure everything had curred.

It's possible the dullcote wasn't mixed thoroughly enough - I've seen it "lump up" like this if not mixed enough (settles out in your airbrush) or if applied unevenly. The thicker (or dryer) parts of the application can look frosty - particularly with Aeromaster dullcote.

If you can figure out what you're doing an learn to control it it can make for a unique weathering effect - dry shooting can be controlled with distance from the surface. Once completely dry, a bit of rubbing with Scotchbrite can leave the appearance of pastel shading.

I always shake it thoroughly and to make sure it flows right heat it in a pan of water for about 10 minutes first. Seems to make it flow better and have not had any clumps, bumps, or lumps or bizarre curing after starting to do that (this is with an airbrush, not a spraycan.)
