Mr.Outback Posted August 17, 2021 Share Posted August 17, 2021 In most cases the order of application of Optimum products is pretty clear. But there are gray areas..... EX: when the wash product contains its own "coatings". It seems M-wash, which worked well on my Subie, has a fluoropolymer component that helps repel airborne metal contamination. Subie had been previously coated with Hyper-seal. Would the previous hyper-seal (3 months old) cause any bonding issues with M-wash's polymer?

Ron@Optimum Posted August 17, 2021 Share Posted August 17, 2021 New formula Hyper Seal should have the same bonding characteristics as the original. Quote Link to comment Share on other sites More sharing options...
