Hmmm I'll have to see how much detail i lose in sealing my models as well. every additional coat removes detail, which is why vapour acetone was a nono for me. Too much lost detail. If its gonna be shiny or smooth it needs to be perfect and hold all the detail of the model, which is why i stay well away from the vapour method.
Im pretty certain the plaster is doing it. but then again plating larger things could be exhausting the electrolyte disproportionally as well, so so many variable when you are plating, it could be anything really!! Could be my voltage, as I never really change it but i doubt it seeing as its worked for the lasrt two years. Might also need to renew my wires, they are looking worn and frayed!
The electrolyte hates organic materials in it. Anything organic will destroy it.

I looked it up in Wikipedia: "Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O." So it contains calcium, sulphate, and water. I am not a chemist, but I can imagine that this would interact with a copper sulphate solution. But bubbles might also be coming from the air trapped in the plaster: it is very porous, so it contains a lot of air.
If you want to test which is the cause, you might put a little bit of the plating solution in different glass jars, and in one add water, in the other add plaster, in the third add primer paint (dried chunks), and in the fourth add PLA. And see which one gets destroyed.
