I considered low temp, but I've warped some of my other toys before trying to use stuff like cerakote (though if you have an all-metal toy, cerakote and gunkote are definitely more scratch resistant, though also more prone to big chips when the finish finally does wear off: though it probably took me like 1000 draws from my kydex holster for that to happen!)
I couldn't help myself and started transforming it recently, since I knew I'd need to do a touch up on some areas anyways: even at 2 days cure, the finish is hard enough that it won't wear off, though the dull did change to shiny on a few parts that rub. Once it's fully cured, I'm going to transform a bunch of times, locate problem areas, and abrade those areas for better paint adhesion.
When these firearm type paints dry, it becomes like a layer of ceramic and so is very, very much tougher than acrylic, which is essentially a thin coating of plastic. Again, even with the partial cure, none of the tabs is showing any paint coming off after putting it through Bat/Ger/Fighter several times.
PS: I started a VF-25A that I'll post pics of soon as well
