Thinning Rust Seal more than 10%

[Guest]

I'm using your galvanized steel Rust Seal. It's really thick and I know in the directions it says you can thin up to 10%. What will happen if I thin it more than 10% because I think it will need it?

If needed, you can thin RustSeal more than 10% with KBS #1 Thinner. The RustSeal will just take longer to cure and you might need more than 2 coats to get at least 5 mils of Dry Film Thickness.

Please let us know if that helps and if you have any additional questions.
