The clue to me is "It was raining outside....." - Dullcoat (much like the dopes used on 1 to 1 ragwing aircraft) tends to soak up moisture out of the air as it is applied (it's called blushing on the a/c and has been known to cause grown men cry in frustration) and about the only way to fix it is to strip it and re-apply it on a day the humidity is lower.

You can't apply dullcoat until it looks wet.  You have to keep misting on coats. The last one can be slightly heavier but the first had better be lightly applied and then allowed to dry and flash out.

like don said, it most likely attacked it. the trick is to first apply a thin coat then let it dry then give it a final coat. never spray till it's got the wet look.

Hi Shipwreck,

I think you just got it on too heavy.  The thinners in Dullcote are pretty hot and I think they need to flash off before they have time to do much damage.  I spray Dullcote over Future with an airbrush.  I thin it about 50:50 with lacquer thinner and mist it on in light coats.  It dries in seconds.  A spray can would be harder to control.

Dullcote went bad

This is the result of rattle-can aplication of Testors Dullcote four days after applying Future. The Future was applied over Tamiya acrylics after about three days. There was an oil/turpentine wash twenty-four hours before the Dullcote application. It was raining outside on the day I sprayed the Dullcote! I tested it on a junk piece with no problem! And, the speckles do not appear on the sides of the fuselage. 

The Dullcote was misted on from about ten inches away; several coates until wet!

Mineral Spirits does not seem to cut it. Laquar thinner does cut it; and everything else. So far the best approach seems to be to lightly sand it untill it is gone.

I have never had this problem before! Any suggestions of what caused this to happen?

Thank you for you input.
