pull rim off the car, wash your rims, be sure they are dry and free of water droplets ( if that's even a word) put index cards between the rim and the tire by wedging them in, then spray the hell out of each rim- I do at least 6 light coats. If u are cheap on the coverage it wont peel off right and u will be scrubbing it off with goo b gone or goof off, I also wrap the valve stem with masking tape. I love this stuff because it is reversible, I even plan on spraying my new rims just to protect the new shiny lip. Hope this helps
