This is a FEC112 Rage Gold Body Filler. Rage Gold is Evercoat's easiest sanding body filler. The unsurpassed sanding qualities are attributed to Hattonite, a unique ingredient, which reduces heat & friction created by aggressive sanding. Rage Gold also contains ZNX-7TM for adhesion to galvanized steel & aluminum. Stain resistant formula reduces the chances of staining & costly comebacks on basecoat/clearcoat paint systems. Use for heavy filling & repair of damaged panels up to 1/4" in depth. Blue cream hardener included.
