I use SuperClean, too, and have tested it with resin pieces, and enamels, oils and acrylics. It removed all of the paints, without any effect on the resin (test pieces were casting blocks from Verlinden figures, and Armand Bayardi diorama pieces).
I use SuperClean for all kinds of paint and finish removal, since first trying it earlier this year. It will remove chrome from chromed parts (tested on Monogram's Red Baron hot rod), and paints from plastic, resin or metal pieces. The chrome dissolved into the solution in less than 2 minutes. I find that the paint will dissolve to a degree, and the longer I let it sit in the solution, but I still usually need to do a little bit of scrubbing with an old toothbrush. But soak times are still 30 minutes or less.
I use different-sized glass jars, depending on the size of the piece. The beauty of using SuperClean (SuperGreen may be just as effective, but I've never used it, so can't say) is that you can use a batch of it more than once. I have been doing 3 passes with each batch, that is, after the third stripping job, I pitch the liquid down the drain (the label says it can be used as a drain cleaner, too). I've even taken to using it to recycle used paint bottles--it dissolves the remaining congealed paint in the bottle, and cleans the labels off.
I used it to clean my airbrush as well. I have put some in the cup and sprayed it through, and I have also soaked parts in a bath of SC.
And around here, it's 8 bucks a gallon at Walmart, can't beat that.
You do want to use gloves, like kitchen cleaning gloves, and even though it doesn't have any caustic fumes, you should still have good ventilation (a good general tip for the workbench, in any case).
In the ultimate use for SC, I intend to try using it to clean the oven
