It’s not galvanisation but it does protect bare steel very well indeed. I have a circular steel plate that was severely corroded although not structurally. After treating with a good quality rust remover.. and then dried off with MAP gas I sprayed this steel plate with two coats of this weld through primer. It resides in my cold and damp garage. Two and a half years later the paint is still doing it’s job(from inside and outside I would guess) as no rust has appeared anywhere on it.On my second can now. It does last as usually only apply it locally to weld repair areas or individual items..Definitely would buy again ### ⭐⭐⭐⭐⭐ Soudure *by on Reviewed in France 20 June 2026* Produit vraiment intéressant pour faire du bon travail 5 étoiles ### ⭐⭐⭐⭐⭐ Good for welding and preventing surface rust *by on Reviewed in the United States 1 June 2026* Really works well as advertised ## Frequently Bought Together - U-POL UPol WELD/AL WELD-2 353 g/12 Oz Zinc Rich Primer - Grey/green - U-POL ACID#8 Acid Etch Primer, Automotive Etching Primer Spray Paint For Bare Metals, Durable Against Rust & Corrosion, Easy-To-Use, Gray, 13 OZ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/420310178-u-pol-789-weld-thru-2-zinc](https://www.desertcart.ec/products/420310178-u-pol-789-weld-thru-2-zinc) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-20*
