Used this to prep the vinyl in my car and was not disappointed. I covered a whole SUV with one can and still had a little left over. Only word of advice would be to do a section at a time so that the whole car isn’t smelling like chemicals for a week or two. I made the mistake of doing it all at once and was practically eating the prep anytime I didn’t have the windows open. Great product. ## Frequently Bought Together - SEM 38343 Vinyl Prep - 13.3 oz. - SEM 39362 Prep Soap for Automotive Refinishing Vinyl, Plastic and Leather Materials, 15 oz - SEM M25083 Carver White Marine Vinyl Coat - 12 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.mx/products/27102850-sem-38343-vinyl-prep-13-3-oz](https://www.desertcart.mx/products/27102850-sem-38343-vinyl-prep-13-3-oz) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-11-10*
