if you can get inside shed garage anything will do , then try to get it warm
next up get hold of an hairdryer and warm the body , then the paint pop this into warm water for about a min , take it out shake it and return to eater untill the can no longer goes cold when shaken
that will make the paint go on nice and thin
use the hairdryer to dry the paint after each coat just watch out for it blowing dust onto the car
