Hi Mech,
OCW and other spray waxes like that are used more as a maintenance wax. In other words a quick and easy way to boost your protection. They only last a number of weeks.
What you'll need is a paint cleaner to prep the surface and then a longer lasting wax/sealant to lay down. You can then maintain this protection with your spray wax/sealant.
We have put together a kit for this containing products, cloths and applicators that is being used by other members of the forum on the Gen 2 MPS with great results
