Frame Painting

[nicrump]

force dry is not needed with 2k PUs. in hotter summer months here i can usually sand and buff out nibs in about 36 hours and i typically let a frame hang the rafters for 2 weeks before building it or up packing and shipping so it will be a bit tougher.

in my experience force drying(at least over 120f) is a risk of die back and blushing or excessive shrinkage. ymmv

The guide for the DuPont clear does not say that it is required.
It actually states 2 different sets of times for Air Dry and Force Dry, including the time "To Deliver".

I actually plan on putting the finished frame up in the attic of my garage for a week before I build it up.
Assuming there will be a few more days above 70, it gets probably around 120 up there.

Don't the pro painters cure the painted frames in large heated oven-like rooms with temps reaching over 400 deg Fahrenheit?

Well again dunno, but I am not sure I would like to have my car "baked" at 400F in case of a repair involving a paint job.

Same clear coat body shops are using...

that would be powder coat curing. which is an entirely different process than wet painting. not even similar chemistry involved.

This is all great advice! Is there a required temperature for painting? I'm thinking about painting it during the winter and letting the frame cure and dry in my basement over the winter.

Between 70 - 80F seems to be ideal.
2K apparently does not dry/cure under 50.
