Hi Nigel, The coat of varnish is conductive varnish to allow electro-plating on plastic, it's I believe more like a powder-coating (atomization... something) for model but it's kind of the same idea. I had success removing it with oven cleaner as you did, perhaps for longer time. I heard that brake fluid removes paint easily, perhaps it would work but I never tried, an other approach is using lye (to unclog sinks), we used that at work (with gloves) to remove a stubborn waxy coating on SLS 3d printed parts and it works for that, so it would perhaps worth a try. But my usual is bleach or oven cleaner, for stubborn conductive undercoat. The "may discolor plastic" on VMS warnings is perhaps a hint that there is some chlorine or bleach in there. 👋🏻
You do these trials so we dont have to! Very informative, thank you Nigel.

I have found brake fluid attacks styrene?
Thats interesting... using bleach, I've never tried that! I always used the old oven cleaner trick. Now i want to try the bleach method! Thanks
Bleach works (most of the time) and it's quick, plus it doesn't melt fingers😊
Hi, Nigel, Revell used to make a Liquid paint stripper which came in a bottle and was brush applied, I wonder if this would have any effect?
Probably?
