Wiper switch knob removal?

I got a plan. I ordered an overlay for the wood grain face from Detroit muscle.
I'm going to carefully wash in warm soapy water. I had it on kitchen counter and looked down and some spice jars...moronicly it hit me.
The spice jar lids are a perfect fit. Now I can spray what needs to be black without too removing the plexiglass inserts. I'll need to find something for the brake light, and trim a piece of card board to fit the speedo glass.
I won't drink any coffee and be well rested when I try to out line the silver.
