Evercoat Super Build 4:1

The Evercoat Super Build 4:1 is a high-build, two-component polyester primer surfacer with the patented 4:1 mix ratio technology. With exceptional filling capabilities, it helps you implement repairs on a host of substrates – rigid plastic, fiberglass, sheet molded composite, bare metal, e coat, aluminum, polyester filler and putties, and SMC. Apply it on properly sanded and cleaned bare metal.

Evercoat Super Build 4:1 has passed the ASTM B117 test for salt spray systems. It is compatible with waterborne paint systems and is also VOC-compliant. Take care not to use Super Build 4:1 on 1K primer systems. Since this has high build properties, you can use this repair expert for correcting light hail damage or wavy panels. You can also use a gravity feed spray gun to spray Super Build 4:1. Allow a flash time of 10 minutes between coats and it is ready to sand in two hours. Start by sanding with 180-grit sandpaper and progress to 220 or 320-grit sandpaper, as necessary.

The fastest service in the business and great coverage. You should keep your free freight on orders over 100.00 like Summit racing does. Allows us to order more often as we need supplies rather than looking for other company deals. Email adds are welcome but your continual pop-up ads are extremely annoying! Thanks for your prompt service. Just waiting with another order for the next free freight. Peter Shamp

If you don't have a paint shaker, it can be tough to get mixed, if it's been setting on a shelf for weeks. Build thick, hardens quickly and sands easily.
