I went round with a wire brush for a long while before applying it. This was last year and I will have to get underneath to inspect it all and find out how effective it was in protecting the underneath over the winter. A.H.Kenny **Q: Does it stay sticky after spraying or does it dry to a smooth finish?** A: It’s good stuff - it dries hard enough not to be sticky - and it’s not a smooth finish -however it’s not too textured either **Q: what colour is it ?** A: It's black **Q: Can this be painted over?** A: Hi, No this stays tacky. It’s and under seal and not like stone chip paint. I like it though and use it on chassis rails etc. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Happy with end product value for money *by A***4 on 29 December 2020* Got this for my wheel arches and underneath body of car seen my mates when he did it a year ago still looks good have 2 tins which is enough to do all wheel arches and give a good coat ### ⭐⭐⭐⭐⭐ Good for protection to underneath your car *by D***D on 5 November 2018* Fantastic product great to under seal your car and protect against wet and salt over winter ### ⭐⭐⭐ very very very slow delivery *by B***D on 14 April 2026* the product is ok done the job --- ## 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.sg/products/65268151-comma-usa500m-500ml-underbody-seal](https://www.desertcart.sg/products/65268151-comma-usa500m-500ml-underbody-seal) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-07*
