There are some resins that tend to sweat if not mixed in the proper ratio or are not mixed well enough. Cleaning with acetone or isopropyl only fixes it for a short time. The paint will stick at first, and then as the piece sweats again, the paint will rub off. There is a way to seal it, as I've heard a guy in the UK use some local stuff (that I can't remember now) that managed to stick and seal, and would take paint well. I guess you have to experiment.
Eventually it will stop, but I've had a piece that I've cleaned with isopropyl several times over a two year period, and it still has issues.

Okay, I'm sure I'm gonna get my booty handed to me once again, but does the Salzo X-wing kit count? I'm sure I've seen builds posted in this forum without being moved for not being SS. And I get that a certain 1/24th scale Y-wing is decidedly not SS. But haven't some of the Nice-N kits also been deemed SS? Some people have said that since some studio models were made as masters and then cast in resin for copies, the resin kits can be SS--or even that they need to be cast in resin. Does SS require that the model be made completely with parts sourced like the originals? Can a SS kit be built from a resin kit that is made from original parts? And I promise I'm not asking to start a fire. I was thinking of the OP. If he had no knowledge of the Salzo kits, or the X-wings made by those guys in South America (is that right), or that Red Jammer kit, should they be mentioned. Not that all or any of these are being produced currently--I don't know for sure.If you don't want to go searching for anything, and I mean this not to sound harsh, this may not be a hobby for you. That isn't how this hobby works. It never has and it never will, probably. No one has ever sold a "turn key" kit, and if anything, I see things going in a more a la carte DIY direction with castings and part availability. You are always going to have to make a Plastruct order, or find something here and there to finish it. That's what most people dig about this stuff.
