Car-Rep Copper Etch & Weld Through Primer Aerosol

CAR-REP Copper Etch & Weld Through Primer 

A professional-grade copper-based etch primer designed to protect metal surfaces while allowing clean, conductive weld-through performance. Ideal for automotive repairs, fabrication, and panel work where corrosion resistance and strong adhesion matter.

What it does:

This primer chemically etches into bare metal, creating a strong bonding surface while laying down a copper-rich coating that resists corrosion and allows electricity to pass through for welding.

Perfect for:

Bare steel, aluminium, and galvanised surfaces Panel repairs and replacements Areas that need to be welded after priming Rust prevention in hard-to-reach joins and seams

How to use:

• Clean and degrease the surface thoroughly 
• Lightly sand if required for better adhesion 
• Shake can well (at least 2 minutes) 
• Apply thin, even coats from 20–30cm away Allow to flash off before welding or top coating
