i called up megs and this is what they said.
i can apply it with a terry or foam applicator. i dont have to remove the armorall cuz its been a while since i last put it on. they said after about a minute of putting on megs #40, i can wipe off the excess and it wont affect the uv protection of the product.
i think ill use the cleaner wipes anyway just so i get a nice fresh coat of only #40.
