I avoid all that..............I found a product a few years back that works GREAT, can be re-used several times, is relatively non-toxic, and will remove both paint and chrome plating.
It is called "Super Clean", and can be had from your local Auto Parts store (U.S.), for about 12 bucks a gallon. It comes in what I call a "People Eater" purple jug.
The only thing to watch with this stuff is that it will take the oil out of your skin just zap!!, so wear gloves.
You can soak plastic parts for several days with no damage to them, and depending on the paint, 24 hours is usually plenty.
I have NO EXPERIENCE WITH RESIN, so do your own experiments.
When done, strain and re-use........up to about four or five times (really haven't got it so dirty it wouldn't work, just got gross).
When done with it, pour down your drain (AFTER straining out all paint), it eats grease, so it's a "win-win".
This, like any chemical, can be HARMFUL IF MISUSED. Please read and follow label instructions. It is a grease emulsifier (parts cleaner), so use with caution and common sense.
