Hazing

I've airbrushed over 300 cars now & lately i get a blotchy haze on the part after it drys, I can remove it with auto polish but just don't know why this is happening. I hate to use the polish cause i then have to remove the wax so i can clearcoat. BTW i use laquer 100% of the time. Could there be moisture in my compressor?

Thanks

Humidity in the air. Get the part in an air conditioned room asap and it will be OK or use a dehydrator. Holding under a bright lamp helps also.
