I have these plastic blinds in my kitchen. They're great because they are easy to keep clean - I pop them into the bathtub with some handy andy to soak and then rinse them clean. But over time they do become dull and grungy and rather than replace them I decided to see how they would look with some spray paint. http://www.home-dzine.co.za/crafts/craft-sprayblinds.htm#
How to paint cooler! Tape-off the entire inside of the cooler with paper and tape. Then spray paint with primer for plastic. Let dry, spray paint with paint for plastic. Voila! See site for more info.!
