On my Spider-Man playfield restoration post, I mentioned making a custom polycarb playfield protector and someone asked if I would show the process of how I did that. It just so happens I had already done a video covering that process.
Disclaimer: I'm not great on video and I can ramble a bit and my camera work is not the best. Also, there are TWO videos, the 2nd one is short but important. I suggest watching both BEFORE attempting to create a custom pf protector. The second video covers a fix (which worked well) I had to do because of issues I discovered shortly after completing the original project.
