Rust Bullet coatings are ready to use right from the can. Due to the exact balance of viscosity, solvent, and active ingredients, it is not recommended to thin Rust Bullet coatings.
If you have been advised by Rust Bullet to thin your product, it is important to maintain formula balance; therefore, Rust Bullet coatings must only be thinned with Rust Bullet Solvent. Thinning or adding any other product to a Rust Bullet coating will compromise the performance and quality of the finished product. Use Rust Bullet Solvent for thinning at an approximate ratio of 3% – 5% by volume (i.e. 1.0 to 1.5 oz solvent per quart of coating). Rust Bullet Solvent should always be used when available. If unavailable in your area, acceptable alternatives would be Xylene, Toluene, or MEK. Do not use any other unapproved solvents for thinning.
Please consult with Rust Bullet Technical Support before thinning your product and do so only when advised.
