Forced curing any side effects?

I was talking with someone about force curing paint either with heat or UV and was wondering if this has no effect on the final product or is it better for durability to allow primers and clears to cure at normal rates?

Can you over-cure? cure too quickly? etc.
 
Force curing with heat or Infra-red, UV curing lamp will not work unless you are using a UV type primer.(different type of wave lengths for specific applications)

Epoxy- no negatives as long as 130 degrees or less.
2k primers-No negatives 140 or less, if to hot could pinhole.
Base- depends on base but good bases 10-20 minutes at 120 would be a good all around safe figure.
Clears- no real point to waste time or money.

When i was on set of OverHaulin, they baked every step of base at 140 for about 30-60 minutes with Diamont and I would have said of all bases, that one would have scared me with that idea because of the polyester content but it worked well for them.
 
Only if you are a production shop.
Unless you buy a production clear that is made for baking, so it will start to dry.
 
what do u recommend out of your clears for a spot repair guy. something u could buff in an hour with extra extra activator lol.
 
I give them the pros and cons, I have a number of clears that at 70 degrees can be buffed at 60 minutes pretty easily.

We have a lot of shops that bake 110-125 for anywhere from 10-20 minutes, every shop is different.
 
I bake (shortwave) the universal at 110 or so for 5min. and once it cools it is ready to go.
 
are you guys talking about air temp in the booth after spraying, or surface temp of the painted substrate?
