Yes, the decals are very durable and can be taken through car washes. It’s an excellent idea to take your car to a car wash when you are ready to pack them away, so they get put away cleanly. Storms, winter cold, slush … well yes… they can take it if you are being careful to apply your decals to a very clean, dry surface. Their ability to be reusable depends on the care you take with the adhesive side of your decal. That said, if you are in the mountains during mud season, or doing some serious off road stuff — I might take my Coveralls off then! But maybe not!
