No, most of the time, thinning is not required before spraying POR-15® 45401 Semi Gloss Black Rust Preventive Coating. This product is already at an ideal viscosity for application with a standard gravity or pressure feed spray gun equipped with a 1.5 mm nozzle. POR-15® coatings are designed to level out and flow into all corners and crevices to provide 100% coverage for maximum rust prevention. However, if you find it necessary to thin the product for easier spraying, you can mix in up to 5% of any high-quality Urethane Reducer.
