Looking for the best way to remove MCW paint . I have tried the Purple Pond and it doesn't seem to touch it. The reason I need to remove it is that the primer doesn't stick to the plastic and if I use tape it pulls the paint off when I remove it even Bare-M-Foil will chip the paint off down to bare plastic. Not sure if I need to do more prep work or use a different primer ? I am using MCW primer.
