Is applying a coat of High Gloss Sealant Glaze on top of All-In-One worth the extra cost and effort?
While a coat of High Gloss Sealant will extend the durability, the real advantage is the increase in the intensity and liquidity of the shine. The question really is, “How much shine do I want?” If your goal is to protect your car’s finish with a minimum of effort and still have a great shine, one coat of All-In-One is all you need. If you desire a head-turning, knock you over, put-on-your-sunglasses shine, reach for the High Gloss Sealant and put on as many coats as you can. It is not unusual for a show car to have a dozen or more coats of High Gloss Sealant Glaze over one coat of All-In-One.
