What materials can I use to decorate a very boring car exterior that won't cut my gas mileage?
I have a honda civic hybrid. It is so beige that I lose it in the parking lot. Could I decoupage areas of the exterior (cut out photos, glue them on, and then put on a sealer)? Use some kind of paint for free-hand decoration (if it isn't absolutely smooth, won't it cause wind resistance)? Use spray paint (Rustoleum?) and stencils? Cut out shapes from contact paper?
In the past, I've used magnets (fall off), bumper stickers (get raggy looking fast).
