BUICK – OEMatch Automotive Spray Paint in CORTEZ GOLD M. (WA4139)

This OEMatching Automotive Basecoat Spray Can is precisely matched to BUICK CORTEZ GOLD M. (WA4139), engineered to deliver factory-accurate color performance for both professional painters and DIY users. With our proprietary adjustable nozzle on the spray can, you are able to achieve professional spray gun level finishes without the need for the professional spray set up.

This paint color is designed as a Tri stage system, which means it REQUIRES APU115 as the undercoat for accurate color match and effect. Make sure to purchase the undercoat along with the WA4139 oem paint. This is an advanced level paint color and is much more difficult to spray and match. All of our OEMatch Basecoats require a Gray AP-7541g Sealer as the ground coat and then needs to be topped with one of our Alpha Automotive Clearcoats for the gloss and protection. This Alpha Automotive Basecoat offers smooth application, consistent coverage, and a true OEM finish. Perfect for spot repairs, panel resprays, or full restorations.

How to 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 Spray Paints require our 1k Epoxy Primer as a ground coat and our 2k Clearcoat Spray Can as the topcoat! 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.
