RCRube:

The spray paints for tinting a canopy that have given me the best results are the Testor's transparent sprays. They are not fuel proof, you have to spray them inside the canopy.

Use 400 or 600 paper to dull the inside before spraying the paint, and use thin coats when you spray. Adding more coats to get the final density desired.

And don't worry about the dulling inside, the paint will make it shiny again.
