Paint and heat

Would it help or hinder the curing and gloss of painted small items, If I paint them in the shop and then take them out and put them in the sun where it is 100 degrees in the shade?
Acrylic enamel with hardener
 

I did that just a few days ago with a hood panel that I had painted the night before. I smelled it first thing in the AM and it was still gassing off so I hung it in the sun for about three hours, then gave it a half hour to cool before mounting. Seemed to work well.
 
If you used hardener the effect will be minimal, unless you are in a big hurry to reassemble. Should be easy to handle in 2 days anyway. I do most of my painting in the fall, 95 degrees in the summer in my shop in the afternoon, so if need be I paint in the morning in the summer. Why acrylic enamel?
 
Yes sunlight will help it cure...it's not really the heat but the ultraviolet rays that does it. Body shops use ultraviolet lights all the time to cure paint and primers. As far as the heat...if you walk in a paint booth right as the heat cycle goes off the paint will still be soft...but when the cool air hits it the paint hardens up. So if you let them bake in the sun for a while and then place them in front of the fan it should help.
 
These are underhood parts, valve cover, oil pan, air cleaner, cast iron pieces. I save the good stuff for the tin and fenders.
 
jason, infra-red, not u/v. we use a spectra-therm 4000 short wave i/r for spot primer, but not for base/clear. we bake at about 140 degrees for 45 minutes or so in the booth. for paint and clear application, the booth temp on the spray cycle is set at 85 degrees. primers and sealer applications do not get forced dried, just thru the spray cycle. here is a link to a spectra therm 8000, the 4000 is a single head unit
