I did my RC's interior in Herculiner about 3 or 4 months ago. I really like it, it's faded pretty good already, but it sits outside with no top in the sun. The key to Herculiner is surface prep. It must be very clean, wipe it down with wax and grease remover right before you apply. I got 3 coats in the front, and 2 in the rear with just enough of the gallon left for future repairs if needed.
