I purchased this Space Mission game about a month ago and have been playing it daily. The playfield is in very good shape, but has a few problems with the inserts. I've noticed an increase in wear around the inserts since we have had the game and would like to do something to protect it before it gets bad. I've read some threads that show how to do a full restoration, but I don't have the tools or the talent to do that. The main problems are cupping inserts and that white circle around each of the inserts. My initial thought was to replace all the inserts, but I have been warned about availability. In another thread Vid recommended painting the white circles with Creatix and an airbrush followed by filling the insert with automotive clear coat. I have finally wrapped my head around the airbrush and clear coat idea. Obviously it would be best to clear the entire playfield, but I don't have a compressor large enough to supply a professional sized spray gun. I also don't have the spray gun. I have three questions
1. What is needed to protect this playfield?
2. Is it possible to clear the entire field using the Harbor Freight airbrush?
3. Where can I buy the clear?
Thanks for the suggestions.
