Vinyl paints (similar to V-Color)

Do you remember the thread from years ago about painting a DD with V-Color paints? I know we’ve mostly moved to accepting RIT dyes and normal acrylics to give vinyl dolls a full color job, but I periodically come back to wondering about vinyl paints as a permanent, color (mostly) certain, and even option. I’ve been looking around, and for the US, it looks like there are several options: Mad Ape Ninja, Sofvi/V-Color, Monster Kolor, and Mr Color that were listed on a Reddit thread I found, in addition to just normal automotive vinyl paints. Has anyone used any of those to color a doll within the last few years? Is there a whole thing somewhere I am missing about this? I really want to try a few out, but I don’t have much money (because of dolls), so I thought I would ask around before slowly picking up a few colors and Obitsu heads over time to try out. I want Urd as a doll.
