You sand dry with 500 and 800, then wet with the 3000 trizact, then you apply two coats of the liquid they supply in sealed packets.
Meguiars also sells a confusing variety of restoration kits. Some have suggested that you can buy the Meguiars liquid separate from the kits and that it is superior to what 3M supplies. They sell a "keep clear" headlight coating in an aerosol can. I have not investigated any of the Meguiars options.
