Hi i finally got some paint on my wagon parts and it kinda turned opaque the first coat went on fine then the last coat turned whitish it is pale yellow(72) colour.The paint is 2 part urethane and i did put flex agent into the paint for the rubber nose.I left it overnight to see if any change and it did not change ...any ideas..? i was going to water sand and paint whole car once its back together anyways but seems like a waste of paint....

I am going to say that it was too humid outside/and/or not enough airflow

   thats too bad      ...back to the paint supplier, for advice?

Yep, humid/cool conditions can cause even a gloss spray bomb's finish to turn out milky coloured (like a film) and semi-gloss in texture.

All of you hit it on the nail head..it was cool and damp(and low air flow),i have it in a heated area now  and it seems to be helping out...i did call the supplier for advice and i painted the fenders and the valance this afternoon with no problem  70 degrees and dry out and lots of air flow !...Thanks Fellas!
