APU140 BLUE – OEMatch Automotive Undercoat Basecoat Paint Undercoat

This OEMatch Automotive Undercoat Basecoat is precisely formulated to serve as the required groundcoat for select tri-stage OEMatch paint colors. It's engineered to deliver the correct foundation tone, ensuring your final color sprays true, matches accurately, and displays the proper depth and effect expected from factory tri-stage systems. This undercoat is mandatory for all OEMatch tri-stage colors that require this undercoat, providing the exact base needed before applying the mid-coat and top layers. It lays down smoothly, promotes uniform coverage, and helps eliminate blotchiness or color mismatch that can occur when spraying advanced finishes. If you are painting a complete vehicle, whether you are just doing a refresh on your OEM paint, changing the color to a different color code, or doing a complete metal up restoration, shop complete vehicle paint kits here.

Build a paint kit:

• On the website we have a paint kit builder that allows you to choose what you are painting and we create a complete cart to make sure you get all of the paint components needed for your project!.
• Build Your Own Paint kit and choose just the items and quantities you need for your project.
• All OEMatch Basecoats require our Gray AP-7541g Sealer as the ground coat and then needs to be topped with one of our Alpha Automotive Clearcoats. Please make sure you at least get those for your project.

What is blending?

Blending (also called "feathering out" or "melting in") means you gradually taper your new basecoat outward so that the metallic orientation, pearl load, and color tone flow naturally into the existing OEM finish. Instead of stopping the color at a hard tape line, you create a smooth visual transition. The clearcoat then covers the entire panel (or the blend area + full panel), locking everything in and making the repair seamless.
