RE: Flat Clear Spray??
Many auto paint suppliers will put paint in a spray can for you. I used PPG Flex and Flat on my Yellow F-22 (in an HVLP gun) and it came out looking great. One word of caution with flat paints, at least the PPG stuff. Don't put it on wet like you would a base coat. Spray it on so it's dry looking on application. Not so dry that it's got a rough texture but dry looking. A wet coat will not dry flat looking. It will have a slight sheen. Definately fuel proof.
