Quoted from rad:Full Mylar sheet - no way.
I'd leave it as is except adding cliffy protectors. Maybe I should rethink that as that's all I've done with the one I have (HUO as well). Will be interested to see if other folks opinions although I'm not inclined on doing much/anything to mine.
I have a HUO TZ that is absolutely pristine. I want to keep it that way, but I also want to play the heck out of it, too. I'm also a traditionalist in that I want to keep my game looking just like it did when it left the factory, so I don't want to 'mod' my game: I just try to protect it.
Here's what I've done to protect my TZ:
1. Installed Cliffy Protectors (Don't forget to install a Cliffy on the switch slot where the ball drops from the wireform.) (I opted to not go with the mini playfield edge protectors as my game didn't need it and it detracts too much from the stock look, IMHO.)
2. Installed Ingo's Clock Board (and put my fully-functional, unhacked clock boards in a baggie and in my coinbox.)
3. Purchased Kerry Stair's (i.e., Mantis Amusement) Slot Machine scoop and Skill Shot scoop.
4. Placed easily removable mylar patches on the playfield in high traffic areas and where the ball drops.
5. Installed a remote battery holder in the backbox.
6. I put felt cabinet protectors behind the legs.
7. Installed Pinbits TZ Plastic protectors to protect the plastics that commonly break. (They also sell custom mylar patches for TZ that might be just what you're looking for to protect the area around the bumpers...)
That's it!
I hope this helps,
Jeff
