RustSeal

Can I top coat RustSeal?

Yes, you can absolutely top coat RustSeal with a solid color UV stable top coat.

There are three effective ways to top coat RustSeal effectively so that the coatings bond & fuse together.

1) Apply your top coat once the second or final coat of RustSeal is dry-to-the-touch and does not leave a fingerprint (usually 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 RustSeal with 300 grit, then apply your top coat.

3) Let the second or final coat of RustSeal fully cure (at least 24 hours), dust the RustSeal with Fusion Self-Etching Primer, let the Fusion cure for 30 minutes, then apply your top coat.

You can feel free to choose the method that will work for you.

How much RustSeal would be needed to coat a standard car chassis (frame and underbody carriage)?

1 Quart of RustSeal should be enough to coat a standard car frame with 2 coats. If you want to do the entire under body carriage and frame with 2 coats, you will want to get 2 Quarts of RustSeal.

Please be sure to read the RustSeal Directions for proper prepping of your under body carriage and frame. The Frame Coater Kit is a convenient kit that gives you everything you need to prep and coat your chassis.

Can I use lacquer thinner to thin RustSeal for spraying?

We do not recommend using lacquer thinner for thinning RustSeal as it is incompatible and can cause issues with the RustSeal. However, lacquer thinner can be used for clean up.

For thinning, we recommend using KBS #1 Thinner and if you do not have that, Xylene is also compatible.

What is the procedure putting body filler over RustSeal?

There are three effective ways to apply body filler over RustSeal so that the RustSeal and the body filler bond & fuse together.

2) Let the second or final coat of RustSeal fully cure (at least 24 hours), scuff the RustSeal with 300 grit, then apply your body filler.
