This machine is in incredible condition for a Paragon. Usually, all Paragon backglass will be heavily bubbled and really hard to recover.
The playfield is in fantastic shape and the cabinet can be fixed without having to repaint the entire machine.

You got yourself a great deal.

Look for the Future Spa by JSA, in the Restoration forum. I posted somewhere a view of the Bally manual showing how to re-assemble the coin door. It is always a delicate and complex phase of the restoration.

Now is the time to carefully insulate the credit button switch. The paper insulator will not make it in the long run and you will be pulling your hair trying to figure out what is going wrong with the machine.

I usually take some heat retractable tubing and slide it over the metal plate in direct contact with the Credit Button. Same thing on the stop plate preventing the contact to go inside.

Pulling the rail will most likely damage them to a certain extent, near the nails. You can always polish the area around the nails and the good part is that you can buy new rails as a last resort.

If you do not intend to repaint the cabinet, I would not touch the rails and use some tape on the wood to protect the cabinet during the polishing of the rails in place. Also, if you replace the rails or take them off, make sure to use little wood screws to re-assemble them instead of these twisted nails.

You did a good job with the rails. Congrats. It is never easy to remove them.

I usually use an eye dropper to fill in the inserts. Applying a spray coat may not be enough.

1- Fill in using an eye dropper.
2- Sand carefully above the inserts.
3- When all the inserts are level with the rest of the playfield, go for a final coat of clear.
4- Wait a few weeks before re-assembling. You may discover some shrinkage around the inserts again. They never stop drinking the clearcoat....
