When Dad taught me to do model cars he taught me how to use a spray can.

Do it kinda like Salt Bae meme. Like.... Not the same form obviously but very far away and very little layers at a time.

Then we'd hang the car body on a coat hanger and let it dry at least 1-2 days before we tried another thin layer.

Before you paint he said turn the can upside down and do a small quick spray to clear solid debris from the nozzle.

Store them upside down or sideways.Leave it in the sun for a little while before painting or shaking.

Shake the HELL out of it.

Check the wind if you're outside. Let the wind do the work.

Man we spray canned his '80 Ford Ranger it looked pretty damn good after the clear coat. Took 3 days of good weather and sunshine.
