Painting my rollcage

I just had a rollcage made and I started painting it yesterday. First we cleaned the cage with mineral spirits, then primed it. We put on two coats yesterday and one this morning. Right now the cage is sitting in full sun. It is suppose to get up to 97 degrees today and I am wondering:
1. The can says to apply the paint at a max temp of 90 degrees. Since the paint is already on the metal will this speed the cure time, or decrease the cure time.
2. Will it have a detrimental effect on the paint if it sits in the sun all day.

The paint is black rustoleum semigloss enamel.

 

You will be OK.

 

Baked enamel!
