What is the procedure putting body filler over RustSeal?

There are three effective methods to apply body filler over RustSeal:

1. Apply body filler once the second or final coat of RustSeal is dry-to-the-touch and does not leave a fingerprint (3-10 hours depending on temperature and humidity).
2. Let the second or final coat of RustSeal fully cure (at least 24 hours), scuff the surface with 300 grit sandpaper, then apply body filler.
3. Let the second or final coat of RustSeal fully cure (at least 24 hours), dust with Fusion Self-Etching Primer, let cure for 30 minutes, then apply body filler.

You can choose whichever method works best for your project. Always review the RustSeal Application Directions before starting.
