I have two WOWA spray sealants. Wolfgang Liquid Spray Sealant and Opti-Seal. According to the directions the Wolfgang needs to be applied to a clean surface without any wax or oils and needs to cue for 8 to 12 hours before topping with a LSP such as wax. The people at Optimum say that Opti-Seal can be topped after about an hour. I can understand that is a difference in formula between the two sealants. However...I am told that you can apply Opyi-Seal to a clean car ( washed and no dirt or dust ) and the Opti-Seal will migrate thru any existing LSP, to the paint. To me this goes against what I have come to understand about sealants. Is Opti-Seal a real sealant as is the Wolfgang and am I really gaining anything by putting Opti-Seal over a LSP ?
