Durable undercoating with consistent texture and strong coverage
This Rust-Oleum undercoating applies evenly and creates a thick protective layer that adheres well to metal surfaces. The texture is uniform and dries to a firm finish that helps reduce moisture exposure. It sprays smoothly and does not run when applied in controlled passes. Once cured the coating feels durable and provides good resistance against road debris and salt. It is effective for covering existing small surface rust and helps prevent further spread when applied properly. The cans spray consistently across the entire set so there is no variation in finish between applications. For anyone looking to protect the underside of a vehicle or metal components this product offers reliable performance and long lasting protection.

Good product, cheaper than at the auto stores
Protects your car from the potassium and sodium salts they use in the northeast. Easy spray application, wear a mask. Better price than you can get at the auto stores.

Great product would buy again.
this product in a rattle can was surprisingly a great product for my application without buying something that you need a compressor to spray on the product goes on easy and so far works well. I live on the coast in Oregon, where it rains a lot salt air does affect the bottom carriage of our cars and trucks little Spand the quality above all right. Would purchase again.
