Aircraft Painting

[170C]

I have a small fiberglass item that needs to be painted. I have some Sherman-Williams JetGlo paint and hardner. I decided to do a test just to see if things would work. I mixed two test batches, one with a ratio of paint to hardner of 1 to 2 and a second one with a ratio of 1 to 1. Don't know which is the correct ratio, but the 1-1 ratio "seems" to be better (but I am guessing). The conditions at the time of the test were obviously horrible and the equipment marginal at best. Temperature was about 72 degrees, humidity was high (raining outside the hangar). Equipment was an aerosol unit with a glass container attached. Much like a rattle can except permitting mixing of the paint/hardner. Sprayed on a bare piece of scrap aluminum. Results--orange peel. I know too much paint(too heavy a coat or a second coat too soon) can result in orange peel. I need help.
#1 - What is the correct ratio of paint to hardner?
#2 - What is the recommended temperature when spraying?
#3 - Humidity limitations
#4 - Am I going to be able to do this touch up successfully with this aerosol unit or am I going to have to got to Harbor Freight & invest in a regular paint gun or possibly an air brush?

Frank, 50/50 is a good mix. Note: "orange-peel" can be the result of too much humidity in the air-supply. If it's humid or you don't have a dryer in your air-supply... add about 10-15% MEK to the mix.
