I'm by far no expert but, have done a bit of painting in my life. It appears you may have some experience at it too. Now, I've got two complete sets of touch up paints for our coach. For some reason, the previous owner ordered two sets. There's four colors in each set plus a clear coating bottle too.
I've had the need to use one of the colors to paint a new dryer vent cover that had blown off during one or our trips. I didn't mix any activators or, enhancers, or orange peel eliminators etc. I just poured some of the color, directly into an air-brush setup and, shot away. It seemed to be dry to the touch in an hour or, maybe two or so. I let it sit anyways for about a day or two then, applied some clear coat that was sent also with the color pack.
Now, you mentioned "Lacquer" in your original statements. I'm not sure but, I'd just about bet that Winne, Itasca and many other coach builders don't use any Lacquer in any of their lineup of paints. As you more than likely know, Lacquer is a strong chemical when it's wet. It will actually loosen some paints and wrinkle the bottom layer if, the bottom layer is not a stronger based or, ultimately cured paint. Seen it happed a few times.
But, I'm not sure just why your paint is not curing. Something's missing in the mix. The company that Winne and Itasca use is called: CDI Paint. It's right next door to Winnebago. It's where many of the folks who attended the last GNR at Winnebago last year, had touch up work done while there.
You are right in the fact that in many paints that are two part, there needs to be an activator. But, I suspect that, they accomplish the two part activation in either another way because they do send out color packs to customers that ask for them. And, if all of the color packs had paints that did not dry like yours, I also suspect that there would more possible complaints on here about the same results.
This is all just a guess at your situation and, my explanation of what's going on. My thoughts here might be for you to try and get a hold of CDI themselves and get it right from the horses mouth on what the issue is. Let us know what you find out, if you would.
