The couple of times I have tried the Brilliant Glaze on my black 2000 Vette (after a complete machine polish and wax)I have found the product to streak, sometimes badly. I would often have to go back over the car with Detail Spray. However, I have now read above that the best way to apply it is with an applicator pad, let it dry, and then wipe off with microfiber rag. Can't wait to give the recommendation application a try.
Cheers,
Bill
