Epoxy Primer +1 Qt. Hardener (1-1 Mix) : desertcart.in: Car & Motorbike Review: Yes it come with a hard black ball in it, that’s pretty typical. And a paint shaker doesn’t work well, get your paint stick out and start stabbing and poking, it will eventually dissolve and it will stay mixed or easy to mix up with a stir or two. It sands nice and hard like you want, and gave a great seal and starting point for my finish paint. I did add a little black tint for a less see through finish and highly advise, it will make it longer to cure but works well. It’s a very high quality primer at a great price point. Review: Black Epoxy Primer/Sealer 2.1 VOC (2-Gallon Kit) – 1:1 Mix DTM High-Performance Primer I’ve worked with a lot of primers over the years, especially on automotive panels and small restoration projects, and this epoxy kit impressed me more than I expected. First off, the 1:1 mix ratio makes life easy. No complicated measuring formulas — just equal parts primer and hardener. It mixes smoothly and has a consistent viscosity that lays down nicely through an HVLP gun. I sprayed it at about 1.7–1.8 tip size and had zero issues with clogging or uneven atomization. The coverage is solid. It builds evenly without being overly thick, and it self-levels well, which reduces sanding time later. I applied it over properly prepped bare metal and previously sanded painted surfaces, and the adhesion was strong on both. It bites into metal the way a true DTM epoxy should. One of the biggest things I look for in epoxy primer is corrosion resistance. After curing, this stuff forms a tough, uniform coating that feels durable and sealed — not chalky or soft like some lower-end options. It sands well after full cure, but it’s also smooth enough that you can use it as a sealer under basecoat if you spray it reduced. Flash times were reasonable, and it didn’t run easily unless I really overloaded a panel. The 2.1 VOC compliance is also a plus for those of us working in regulated areas. For automotive restoration, frame work, small fabrication projects, or even industrial equipment refinishing, this kit delivers professional-grade performance at a competitive price point. The finish looks clean, uniform, and lays a solid foundation for topcoat. Overall, this . Easy mix ratio, excellent adhesion, durable corrosion protection, and smooth spray characteristics — I would definitely use this on future projuects, ## Features - Custom Shop – KEP Series Anti-Corrosive Epoxy Primer / Sealer is a 1 to 1 Mix Ratio high performance primer specifically designed to be used DTM (Direct to Metal).

Depending on the project I'm painting. I have to say this time I got a bad batch. I mixed it according to the mixing ratio as always but this time when I went to sand it smooth so I can seal the motorcycle tank fender and truck doors to paint them today. It was hard as hell and took me 2 hours just to sand down half the rear tire fender. I quit for the night mind you this was after getting off my regular job last night. Was very aggravated last night when I should have had everything done in 2 hours.Not all are bad, but this one was. ## Frequently Bought Together - Custom Shop - Gray Epoxy Primer/Sealer 2.1 VOC (1/2 Gallon Kit) Anti-Corrosive DTM High-Performance for Automotive and Industrial use Kit = 1 Qt.
