Yes, it is possible to cover a darker colored item in white or a lighter color of Peel Coat. The project will require more than the usual amount of Peel Coat product to fully conceal the original color. Rust-Oleum has found that using a Peel Coat Gunmetal mid-coat helps with the color transition and results in fewer overall coats. 

Before starting the project, remember to clean the surface with soap or another cleaning method, rinse and let dry. Mask off around the area to be coated. 

In order to produce nice, clean lines of the Peel Coat coating, it is recommended to remove the masking tape when the last coat is still wet. If for some reason, the product dries before the removing of the tape, light spray the edge of where the tape and coating meet and quickly remove. The coating typically begins to dry 5-10 minutes in between coats.

No. Rust-Oleum does not require or recommend usage of a primer prior to applying Peel Coat.
