I was asked to give a full wash and wax on a 94 Toyota Supra from a referral of a STI owner, and yea, it is a black!! The car has previously been polished and is in an excellent condition. The current and previous owner don't drive the car in rain and snow, the car only shows up in good weather. But I heard a bad news when I came to the store. The owner said a technician has screwd his paint from washing, and I can see millions of moderate scratches in a cloudy weather. The wax was in average but left some stains which was very difficult to clean.
