U-POL Weld #2 Copper Rich is a 450ml weld-through primer for panel repairs: spray it onto the bare overlapping faces of a new sill, patch or panel before spot, MIG or TIG welding, and the joint keeps rust protection inside the seam. Its high metal content conducts, so you weld straight through it, and it dries fast.

Good to know

• Where exactly does it go? Weld-through primer goes on the bare mating faces of panels before they are welded together, protecting the overlap that can't be painted afterwards; the outside faces get normal primer later.
• Why copper rich? It is highly conductive, which suits spot welding, and its copper colour is easy to see on bare steel, so you can tell the flange is fully covered.
• How should I weld through it? Spray a light coat, let it dry, then clamp the panels tight; welding through any coating gives off fumes, so extract or ventilate well and wear a suitable mask.

Which one?

For the zinc version, U-POL Weld #2 Zinc Rich (WELD/AL); for priming bare metal that isn't being welded, U-POL Powercan Etch Primer (PCEP/AL).
