Can I use lacquer thinner to thin RustSeal for spraying?

Lacquer thinner is a frequently asked-about solvent, but it is not compatible with RustSeal for thinning. Here is what to use — and what to avoid.

⚠️ Do Not Use Lacquer Thinner to Thin RustSeal

Lacquer thinner is incompatible with RustSeal and can cause product failures when used as a thinner. Lacquer thinner is acceptable for clean-up only — never for thinning.

✅ Recommended Thinners for RustSeal

1st Choice — KBS #1 Thinner: Our recommended thinner, formulated for use with RustSeal.

Alternative — Xylene (Xylol): A compatible substitute if KBS #1 Thinner is not on hand. Works well for thinning RustSeal.
