I have some bare metal and some areas of existing paint and other primer.** A: As long as you sand the paint and medal with at least 220 grit sand paper fine. I have been using it on fiberglass/paint. It will show you the high spots and lows. You could also use a contrast material to make sanding easier to get your smooth finished product. Hope this helps. **Q: How long does it have to dry before recoating?** A: It is mainly depending on environmental temperture. Watch the first coat, when it flashes, it is ready for the next coat. A little extra wait wont hurt. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on May 25, 2022* ### ⭐⭐⭐⭐⭐ Review *by A***R on September 29, 2025* ### ⭐⭐⭐⭐⭐ Review *by P***W on April 11, 2026* ## Frequently Bought Together - SEM 42013 Grey High Build Primer - 16 oz. - SEM 39683 Grey Self Etching Primer - 15.5 oz. - SEM 39673 Self Etching Primer (Black, 15.5oz) --- ## 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.pt/products/13813132-42013-grey-high-build-acrylic-primer-16-oz](https://www.desertcart.pt/products/13813132-42013-grey-high-build-acrylic-primer-16-oz) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-24*
