Any idea what would cause Humbrol #1325 (actually their clear color green) to dry opaque white?
It was stirred, not thinned, painted over a clear canopy protected with two coats of Future. A new brush was used, it was left to dry under a plastic tub. It's definitely the paint that has opaqued, it's not the canopy plastic.
Any suggestions on how to avoid it in the future AND more importantly how to clean up the canopy (which amounts to removing the Clear color without removing the future?
Thanks.
