We got our Scion Stingray in July, paid extra for the Finishtouch exterior protectant. We have never washed it with water, just waterless car wash by Smart Wax. My daughter got a smart idea one day and "hosed " it off. So next time I go to waterless wash it I can not get the water spots off the hood. With the supposed sealant I didn't think we could get water spots. I don't know if I should try waxing (I read here somewhere that waxing the sealant removes the sealant) or use something else or if I should take it to the deal and say "what's up?!" We paid good money to not have this problem. Any suggestions???
