If you have used EZ Creme glaze on your car, proceed with a deep cleaning wash, decontamination, and then machine polish the car. If no correction is needed, then just perform a very light polish to ensure residual products have been removed from the paint. After polishing, wipe down with 50% IPA solution to remove any polishing oils. Then apply your paint coating. If the paint is not properly prepped, your paint coating may not perform as expected.
