How much RustSeal is needed to coat a car frame?
One quart of RustSeal is typically enough to coat a standard car frame with two coats.

If you plan to coat the entire underbody carriage and frame with two coats, we recommend using two quarts of RustSeal.
Do I need to prep the underbody and frame before applying RustSeal?
Yes. Proper preparation is critical for best results. Please be sure to read and follow the RustSeal Application Directions for correct cleaning and surface preparation of your underbody carriage and frame.
Are there kits available to prep and coat a vehicle frame?
Yes. The Frame Coater Kit and the Large Frame Coater Kit are convenient options that provide everything needed to properly prep and coat your chassis.
