When the car is waxed or sealed with a resin sealant... then what should your washing regieme be? Snowfoam and rinse/dry only?
what ever you want within reason..
(worth noting Super resin polish wont last long at all its a polish not a dedicated sealant)
i snow foam, wash with shampoo rinse and dry,...
longevity depends on a lot of factors but using a decent car shampoo in the correct dilution shouldn't harm the wax/sealant
