Thanks for the quick responses. I use Harry's paints and some of Charles's as well. I try to pay attention to the gloss vs. high gloss vs. satin as well. The humidity and temperature are of concern as I live in the South and we have recently experienced multiple 90 degree days with heat index in the low 100s. I run a dehumidifier 7 x 24 and AC when I paint in the garage. If I am going to bake a piece at say 200 degrees as soon as it is sprayed, the outside temperature shouldn't matter. Humidity might. But, I am thinking heat is the problem AND I am over baking. I am going to test inside oven temperature using only one 75 watt bulb and try another piece to two.
There was a mention to sand the primer coat. I have never done that. I have at times lightly sanded/steel wooled before adding another coat of paint.
Thanks to all who responded. Hoping your thoughts and ideas will bring a little shine to my cars....
