I used heat from utility lights that you would use in a garage. When painting the temp should be 25°c.
First prime, cover the entire area. Allow 24 hours to dry then paint thin coats opposed to thick coats. Get good coverage, I usually paint the tough areas first, like the corners or detail areas and then a good pass over the entire area. Once it's dry check the surface and make sure that there is no blemishes. Now it's time to add the clear, basically repeat the same steps. In between coats you'll want to use 800 water paper and do a wet sanding. Then go to 1500 and then 2000, you can go to 3000 but that's a preference. Good luck man...GM
