The PA Esclate Lotion is like a paint cleaner with abrasives in it and has some oils in it that works in synergy with the Master Sealant. So acuRAS82 recommendation of the coating prep polish is something that will work. Or just do a panel prep wipe product wipe down after the finishing polish step and you are good to apply Master Sealant with good results. So something that leaves the paint bare is what I would go with before applying Master Sealant.
