Q: I understand that RustSeal should be top coated if it will be consistently exposed to sunlight. So, how do I top coat RustSeal with a top coat paint so that the top coat paint adheres?

Asked by: suarez - 8/31/2013
A: There are three effective ways to top coat RustSeal effectively so that the coatings bond and 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.

Q: Can you mix two colors together ie: gloss black and silver to give a bright metallic black paint? Thanks John Lattner

Asked by: John - 5/2/2014
A: Yes, you can mix colors of RustSeal together and then apply it. That is a very common practice.
It is always best to just mix what you want to use as we have not tested long term stability in the can of RustSeal when mixing together 2 or more colors.
