Air Temp vs Metal Temp

Quick question as I've searched and not been able to 100% find an answer, either that or my searching is bad which is probably the case :)

Anyway, if I have some parts that I set out in the sun and get the metal temp up around 75 deg is it OK to shoot them with SPI epoxy even though the air temp will be in the lower 60's? I would then leave them in the sun until I can move them to my heated garage to finish curing. It's just some leaf springs if that matters.
