JJP Guns and Roses Pinball Posts and Playfield Issues

In this vid I show the parts I used to compress the clearcoat around the posts that were wiggling. I also replace the T-Back fasteners under the playfield to make for a better tightening of each post. The game has been great for the last several months since I shot this repair. Let me know if you've done something different that might work better.
Thanks and Happy New Year!
