Description
A cream hardener designed for use with U-Pol and Isopon polyester body fillers. The red colour makes it easy to see when the hardener is fully and evenly mixed through the filler, rather than guessing.
Mixing: Mix thoroughly at the ratio specified on your filler's packaging, typically around 2 to 3 percent by weight. Too much hardener can cause bleed through once primer and colour go over the top.
Type: Cream hardener (benzoyl peroxide based)
Colour: Red
Use: Curing agent for polyester body fillers
