Sticars's car decals

What It Is: Intimidating flames and sleek racing stripes are perennial favorites among drivers wishing to jazz up their cars. For those looking to use their car as a canvas without the permanence of paint, there are a variety of stick-on options, ranging from checkerboard swooshes, vibrant daisies and even do-it-yourself designs.

How to Get It: Sticars offers 20 magnets that include birds, polka dots, dragonflies and skulls. VWDaisies.com's sunny, adhesive vinyl flowers come in 11 colors and six sizes.
Auto Body Art's offers graphic vignettes of a cattle drive or a horse-race finish meant for the side panels of a car or a horse trailer.
The Stars car-graphics kit, from Daydreamer Designs, contains 20 stars of assorted sizes to add razzle-dazzle to any vehicle.
SignSpecialist.com has a library of more than 1,000 flames and stripes designs, but amateur artists may also submit their own drawings. To see if a design would work on their car, customers can upload a photo and the company will email a rendering of the design on the car.
