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. |
