I have a 1991 Black Notch Coupe. I love black as a color and know it is a PIA to keep looking good. My problem lies in when I wash the car it looks immaculate and really good. The moment I put some spray detailer on it is streaks like mad. I have tried several kinds and have had little luck. The first couple of times it happened I chalked it up to being out in the sun and absorbing heat. The last time it happened it was cool and had just washed the car. Any ideas to help me out? :shrug: I have tried Optimum Spray Detailer (works ok) Poor Boys Quick Detailer(streaks) Wizards( Does the best job so far), Turtle Wax black box detailer(streaks) Turtle Wax wax as you dry (streaks), CroftGate(streaks). The car was painted 2+ years ago. The only thing I have done since I acquired the car is Poor Boys Black Hole. I have thought about stripping everything wax wise (starting with clay bar) and starting from scratch. ANY ideas or products would help.
