Quoted from vid1900:

Auto clear, aka 2PAC, is actually WAY easier than any other topcoat:
1. In a few hours, it is totally cured. In 10 minutes you can apply a second coat and the whole playfield is done. The time you save vs. 10 coats of water based poly is enormous.
2. All the cupped inserts or playfield dents are simply filled with an eyedropper. The cupped inserts are now reinforced by the 2PAC.
3. The 2PAC is COMPLETELY CLEAR - there are 1x1" cubes of it at the dealer. Just try to make a 1x1" cube from water poly - it will be solid white.
4. The 2PAC will not run down the playfield holes or slots when spraying the playfield flat on it's back - water poly runs like a duck's ass.
5. There is nothing tricky about it, except that you have only 2 hours to empty your gun. Even if you forget and the gun is solid 2PAC, a new gun is only $9. The price of a disposable paint roller.
6. Once you try 2PAC you will cringe every time you see your old posts defending water poly. No one ever goes back. Ever.

Quoted from Greybeard:

Sooo. Where are we on the 2 part in can? I want to try a clearcoat. If it works out then I can look at more involved equipment.

Quoted from metahugh:

This is the primary reason why I haven't tried clearing myself. I don't feel safe enough laying down clear in my attached garage. I would try it in a completely separate building but I would want a full setup: clean air mask and a vacuum wall to catch the particulates. I would hate to use this stuff in a residential area and harm my family or my neighbors.
