BLUE-CAR High-Build Acrylic Filler Primer 5:1 KIT (Primer + Hardener)

BLUE-CAR 2K High-Build Acrylic Filler Primer Kit is a complete professional system supplied with the correct quantity of hardener.

Its high application viscosity allows thicker coats to be applied, effectively filling sanding marks, deep scratches and surface irregularities left after working polyester body fillers.

The primer provides good flow and uniform coverage while creating an insulating layer between polyester fillers and acrylic topcoats. It offers anti-corrosion properties, cures quickly and is easy to sand.

The included 160ml hardener is the correct quantity for the supplied 800ml primer, providing the required 5:1 mixing ratio.

Available in Graphite and Grey to provide a suitable base for different topcoat colours.
