Paint stripper

Could you be thinking of Chameleon? That was the best I ever used,I still have a bit left that I use sparingly when all else fails. I think someone came up with the formula for it recently so there should be something in the archives.

Seems to me there was a commercial hobby paint stripper whose name escapes me at the moment e eeavailable before “EasyLiftOff” that worked well.  

The only problem with petroleum-based paint strippers is that, while they removed the paint, they also removed some of the plasticizers from the molded plastic which made them brittle and allowed release of some of the internal stresses of the molding process, sometimes causing spontaneous shattering of the shell or warping.  This is a non-chemist/plastics expert explanation of some of the failures I had especially early on (1960s/70s).

Is Scalecoat II Wash Away Paint Stripper/Remover for Plastics formulated the same as the Chameleon paint stripper? They look similar.

Ordinary 91% isopropyl alcohol and butyl cellosolve (2-butoxyethanol).
I customize my mixtures depending on the plastic I am stripping, 5% butyl cellosolve for ABS and up to 10% butyl cellosolve for styrenes.  For old Tyco and AHM models there is a fine line between removing the paint and causing the plastic to craze, so be careful.  Also be careful not to get water into the mixture, 91% isopropyl is the lowest concentration of isopropyl that will work.  Note that a few percent of butyl cellosolve in water with a trace of a surfactant is an excellent decal setting solution (e.g., MicroSol, Solvaset or Champ decal setting solution).  Again, too much butyl cellosolve with dissolve the decal or even start to remove the paint.

Butyl cellosolve can be bought in most paint stores that supply professional painters, in gallon and 5-gallon cans.  It is used as a thinner to slow the drying of lacquers by cabinet & furniture makers, etc. for a high-gloss finish.

I forgot, the new version of Walthers Solvaset no longer uses butyl cellosolve.  It doesn't work as well as the old Hobsco.

Solvaset was 40% Glycol Ether PM 60% water.
