Ionly open one can, and the unuesed ones cannot be returned ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United States 7 September 2026* Good ### ⭐⭐⭐⭐⭐ Really good product of its kind *by on Reviewed in the United States 2 October 2024* I'm quite impressed with this, enough so to follow this can with a case of 12. Goes on marginally prepared surfaces quite well and has a nice sheen to it. Goes right where you aim it and no overspray to speak of. Dries well and relatively quick. I sprayed the trunk of my 1947 Ford as well as under the fenders after basically just vacuuming the surfaces and wiping obvious messes up. I will try to update this after some months have passed of usage. ## Frequently Bought Together - Permatex 81833 Heavy Duty Rubberized Undercoating, 16 oz. net Aerosol Can - Rust-Oleum 248658 Stops Rust Reformer Spray Paint, 10.25 oz, Matte Black - Permatex 80072 Undercoating, 16 oz. net Aerosol Can --- ## 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.fr/products/457564577-permatex-81833-heavy-duty-rubberized-undercoating-16-oz-net-aerosol](https://www.desertcart.fr/products/457564577-permatex-81833-heavy-duty-rubberized-undercoating-16-oz-net-aerosol) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-10-01*
