I have found that the generally everyone agrees that 303 aerospace protectant is the best product to use on things like door panels, plastic parts, rubber parts, and just about everything else in the car. However it does not say to use on cloth. Is there a product I can spray onto my cloth seats to protect them from spills, etc? The dealership sells "resist-all" which nicely waterproofs the cloth interior, so I'm looking for a cheap alternative to do myself. Any suggestions?
