Gloss coats getting less glossy?

Help, I'm working on a statue/model, and I've applied several coats of Krylon clear gloss which looked fantastic, however certain parts where masked off and after removing the masking tape I recoated the figure and again after a few hours. I left it outside in the hot 110 degree Arizona sun and now it seems the model is almost matte. I reapplied yet another coat this morning and it's still not as glossy anymore. Can too much gloss coats have the opposite effect? Did the sun have a negative affect? Should I try purchasing a lacquer, varnish of some kind to get the super gloss look again? Any tips, Thanks!

Unless it's a 2 pak paint system, all paint systems can suffer from 'blush' which kills the gloss. Lacquer, enamels and acrylics can all dull in intense direct heat.

If too much heat is applied to the drying time. Wait for it to become really dry and hard, them light sand and respray. Don't let it dry in intense direct sunlight.

Ya I usually like to let clear dry inside where it is cooler and more importantly less humidity.

Thanks everyone, i think everyone is right, the sun killed it. Never again lol I'll sand it down and start over.

I tend to do a lot more sanding at high grit between coats in warm weather, then do a final thicker coat and dry it inside.
