The vinyl wont be shiny after the paint removal, @kichigai from what I know it dulls the finish once you put abrasives on the plastic.
As far as I know, yes. It looses the luster. I dont know if plexiglas polish could resurface it, but if you dont use the right cloth it might scratch. I do a lot of work with that so I've become quite aware of the limitations of stripping plastics from solvent based paints. Best of luck with it, man.
I've had a few different toys turned "blank" and yes you will lose the shine for sure. It doesn't really matter if you plan to get the toy repainted though. Also you can have the shine added back on with a clearcoat if you really want to. I had toy with very damaged paint stripped then clearcoated(I wanted the UV protection)and it was super shiny afterwards and has stayed that way for years.
Someone told me that if you remove paint with acetone or thinner that you immediately have to submerge in cold water to stop the process... it could have been warm water.... sorry my memory is a bit fuzzy!
Wear your respirators, kids. Saw quite a few resin-slingers end up in the ER for trying to tough it out without one.
@hellointerloper yeah, I guess if you want brain damage, that's the best way to go about Possibly! Wait... where am I?!
This particular figure would be a good candidate for stripping. I would use acetone, as lightly as possible. The black vinyl can't really be stained by colors as a lighter vinyl will sometimes be and a small amount of luster loss can be helped with a smidge of baby oil. Just my opinion, I love this figure and would be happy to strip it for you.
What most people don't understand about stripping a toy is it often leads to tons of micro airbubbles on the vinyl's surface. They aren't overly visible, so I guess that's not a big deal unless you are a stickler. Definitely use V-color thinner as opposed to acetone because it's less damaging. But you have a heavy textured figure that is fully painted in metallic, it's going to take a lot of chemicals to strip completely and there will likely be damage to the vinyl even if you clear coat it afterwards.
Just paint it in black vcolor, problem solved. It will look solid black, have a gloss and no one would know
