Many people don't know that these polymers will react this way with ABS. The reason why is the open bonds bind to the styrene in ABS and break the bonds that hold it together. ABS is Acrylonitrile butadiene styrene!
This is the same reason you would not want to put the resin in a Solo cup, they are extruded styrene.
I can't comment much on the enamel paint, because that is vague and so many companies use that with various formulations. But to be sure all of these polymers will act as a solvent for paint when uncured.
Regarding smoke during curing, that happens if the exposure energy is too much for the resin formulation or the resin is getting too hot. It will start to vaporize which is likely the smoke you see. If it is just happening because of the UV, then you likely need to request a blend with less photoinitiator from whoever you are buying from (us, SpotA, etc). That will cause it to to be less exothermic but also cure slower.
If it's happening because the resin is getting hot from a DLP fan blowing on it or something, I would recommend redirecting those exhaust fans away from the resin bath. Heat reduces the life of the uncured resin as well, so it's never great to have too much on your stuff when uncured.

P.S it was not makerjuice.

Also they talk about "you can sit right next to ours and not need a gas mask." - well. Actually I worry less about the odor than I do the smoke that I see coming off of it when printing. There isn't a lot but seems like it can't be great to breath it. I mean really - what is the worst than can happen right?
Not trying to pick on Makerjuice here. Josh is good guy and has been very helpful. For my case I am going to use a 4" bilge blower
above the build surface to vent fumes outside. This is a great blower BTW. 12V and adjusts wonderfully from 3 - 12V. Moves a lot of air and is quite loud at 12V.

I made a post about how it dissolves ABS.
