Thread: removeing duracoat (or similar )

have a stunning custom-built long-range that a fellow built, and I brought it off his estate

it has stunning wood stocks and everything, and it's almost like he skipped the last part and painted the thing
It looks like plastic and doesn't suit the rifle at all

I want to do it properly and rust blue it, but I need to get it off
It's not just paint, it's some sort of proper firearm paint like Duracoat

how do I remove without damaging the steel
