I know both OMNI and Shopline are both PPG budget paint lines. I've shot with OMNI for over 10 years. Overall, I've had good luck with it for what it is. When I went to get some for my last project, I was told OMNI was being phased out and Shopline was the new OMNI. The Shopline was utter garbage. What took 3 coats in OMNI took NINE coats in Shopline. It was like colored water. My paint rep swears up and down they're the same paint but I don't buy it. I believe the hardeners and reducers may interchange but the paint itself is different. Anyone who has sprayed OMNI knows it has a very distinctive smell. Shopline does not. Does anybody know the real deal? I hate being lied to. The rep goes as far to claim Shopline is superior because only they can sell it since they are a Platinum distributor yet any old paint store can sell you OMNI.
