![]() A 1k, you’re waiting for the evaporation process which could take a week you know to fully cure, sometimes two weeks. That’s why 2Ks are a lot more durable because you’re putting in a catalyst to make your paint cure hard. Some people call it a hardener some people call it an activator, and it’s the same thing. 2K cures by activating, by putting in a hardener and activator or hardener, just the same thing. How does a 1k get hard? 1k gets hard by the solvents in the 1k evaporating out, that’s how it cures. So just make sure your 1k is basically cured. Make sure it’s really dry because if it’s not, whatever paint you put on top of it, especially automotive paint, the solvents in it will basically eat it up and you could get a chemical reaction. Maybe just make sure it’s dry, you let it sit for a day or two. We sprayed 2k automotive paint over it and it worked, so you could paint over it.

But you don’t want to seal this before you put paint on it, so what I’m going to do is get my 1K Sealer and I’m going to hit all the spots and the little bit of metal. ![]() So ideally, you could spray over it, you could. I was sanding some glaze over the spots here on the Van Project and then I cut through to the filler. Sometimes you’re doing bodywork and then you cut through to metal, or you have some glazed putty, you really never want to paint directly over that. I have a 1k Sealer here by NASON, this is good to spray over body filler like raw body filler. But if they gave you a 1k sealer, I’m thinking it’s an aerosol can. So if they gave you that you could go either way. Can I use that under 2K Urethane single stage? The question is – the paint store gave me an “Autobody Master Acrylic Sealer” ready to spray.
