IR lamp question

[Pretending702]

You guys will eventually get sick of all my questions but before that I have another:

with an IR lamp pictured below that covers say 31x24 every fender, door, hood, etc is going to require overlap to get full coverage. So the question is, can you overture epoxy primer? Meaning one spot gets 30 min and the overlap section gets another 30 so 60 min total. I know if it's too hot it'll blister so lets say keeping the panel at around 125 degrees?

SPI recommends 110* and to not go over 120*, that is for the Euro clear, I didn't check the other clears. Epoxy has no bake recommendation listed, but I have put black epoxy out in the sun in the summer with no problems, and that is most certainly higher then 120*.
As far as the overlap, I would use a IR temp reader to let me know where to move the lamp, but since heat rises, I would start at the bottom.

epoxy doesnt cure quick and react to cure lamps like urethanes do. it will certainly cure epoxy but it takes heat and time. a lot of time. 30-60 min for urethane may be like 8-12 hours for epoxy. those #'s are not accurate. i am just trying to point out the difference.

I can usually dry sand epoxy after 3 hrs under the lamp, but
not all lamps are equal of course.
