I agree with everything others already said , especially reading Vids guide on frisketing .
I restored a Fast draw using frisket ( https://pinside.com/pinball/forum/topic/fast-draw-playfield-restoration-first-ever-attempt-#post-4461751 ) some time ago.
Sometimes when the painted area is very thin or with intricate shapes you must be on the lookout when removing frisket and be ready to cut with a xacto blade the edge of the paint so as to minimize paint lifting along with the frisket.
Good luck
