Applying DMT Dash Overlays

Is your overlay a decal or die-cut thin plastic like mine?
They're decals.

Trick from my plastic modelling days- mild oven cleaner makes a great stripper on plastic. Scrub with a toothbrush (Old one... :)). Try not to get it on the chrome if you're trying to save that. Wash thoroughly in soap and water afterward.
I'll try a small section.
