I used it on a 90 degree day, using a hvlp harbor freight spray gun, i sprayed at 30psi to the tip and used a 1.7mm needle and tip. the primer was drying before it even hit the car ( due to the 90 degree temp). But even then, it still stuck and created a nice layer of primer. After sanding with 600 grit to get the texture feel out of the primer, it still covered the car and sanded very nicely. Next coat will be sprayed with a 2.0mm tip and needle to help prevent the paint from drying before it hits the car. ## Features - Custom Shop – DTM Series High Build Urethane Direct to Metal Primer Surfaceris a 4 to 1 Mix Ratio high performance primer specifically designed to be used DTM (Direct to Metal) .

Comes with hardener. But at 4:1:1, you’ll need a 3.0 tip and 50psi just to shoot. I doubled up on reducer and with 2.0 tip @25psi, and almost wide open, 80*, shoots flat, and a few thin coats, build up is great and good adhesion. You need to work out what’s best for you. There are better filler primers, but this is consistent. ## Frequently Bought Together - Custom Shop - Gray DTM High Build Urethane Primer Surfacer 2.1 VOC (1-1/4 Gallon Kit) High-Performance Direct to Metal Primer for Automotive and Industry use Kit= 1 Gal. of DTM Primer and 1 Qt. of Hardener - TCP Global Premium Paint Mixing Essentials Kit with 12 Cups, 12 Sticks, 12 Paddles, 12 Strainers & Can Opener - Restoration Shop UR70 Medium Urethane Reducer (Gallon) for Automotive Paint and Industrial Paint Use - High Performance Automotive Grade --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/492286193-custom-shop-gray-dtm-high-build-urethane-primer-surfacer-2](https://www.desertcart.co.th/products/492286193-custom-shop-gray-dtm-high-build-urethane-primer-surfacer-2) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-03*
