Is Rubberized Rust Encapsulator Better Than Under Coating?

Posted: June 26, 2019 By: MattM

When restoring or repairing a rusty vehicle you might have a lot of products to choose from and each of them have a use that they excel at. Rubberized Undercoating is the industry standard for under car coatings but it isn’t always the best to use. With the introduction of Rubberized Rust Encapsulator we’ve married our two favorite under car coatings into one that might be better for your project.

When is Best to Use Rubberized Rust Encapsulator?

The general consensus is that Rubberized Rust Encapsulator is the perfect middle ground between a standard rust paint and rubberized undercoating. When doing repairs on the underside of a rusty vehicle you may find that you still have residual rust or pitting that you can’t fully remove. If you simply spray an undercoating on top of the entire area you aren’t stopping the rust and you may notice the rust creep around the undercoated area over time. This is because the rust is still growing and it may spread to the welded/repaired areas. If you’ve ever seen an old undercoating job where the undercoating is peeling off of the metal it could be because the rust has spread and is delaminating the undercoating.

These instances are where it’s important that you remove or stop the rust before top coating. Eastwood Rubberized Rust Encapsulator stops the rust by using our proven Rust Encapsulator formula that seals out oxygen encapsulates the surface. We added epoxy into the formula as well to help with adhesion and sealing properties. Rubberized Rust Encapsulator finally has high-flex agents to make it flexible and durable for exposure to road debris. We’ve found that Rubberized Encapsulator also has a more fine textured finish versus a traditional undercoating which makes it nice for restorations or custom cars where you want a more neat appearance.

Application of Rubberized Rust Encapsulator is simple. Start by removing any loose or flaky rust and wipe the entire area down with PRE Paint Prep. Once the PRE flashes off you can apply a medium coat of Rubberized Rust Encapsulator. A medium coat will give you an even coat with moderate texture. You can apply additional coats for extra build and coverage but it isn’t necessary. Just keep in mind that extra coats may make the surface texture more rough with each coat. If you’d like ultimate durability you can apply traditional rubberized undercoating on top for a highly textured surface that will resist 99% of the road debris you’ll encounter.
