In a bizarre turn of events I will be working on two Space Invaders pinball machines (one is mine and the other is one I was going to buy but missed out on//its a long story)..ANYWAY..the one I missed out on the new owner is asking me if I would restore the game for him. I explained the cost of a repo and the overlay. He wants to go with the overlay. I have never applied an overlay before so I have a few questions about the process:
1 - After I sand down the playfield do I have to do any type of prep work to the wood before I apply the overlay?
2 - After overlay is applied, do I clear coat it? If so, about how many coats do I apply?
I will look up youtube vids of the process (if any exist) but I also wanted to get educated by the pros on here.
