Quoted from High_End_Pins:Two weeks is what I recommend.
A lot of talk on here centers around playfields but the reality is it’s about coatings. The fact it is on a playfield introduces very few additional concerns.
The playfield is still a playfield and the clearcoat is still a clearcoat. No amount of waiting will change that if the products are good and compatible.
The products I use recommend overnight cure before assembly or polishing.
72 hours prior to decaling. That is because you would be trapping solvents under the decal installed if you did so prior and they will likely bubble or bond permanently to the surface.
Next day delivery on an automobile.
I like to sand and polish in 5-7 days then assemble so well past the minimum.
By the time that takes place and the game is playable we are usually at the two week mark or so.
A few test plays and it goes out so typically the finish is a month or more past the acceptable delivery date once the game is back home.
Makes you wonder why you would spend the money on a Mirco playfield. Mirco seems to be the only game in town for an FH playfield. I ask this as someone who wants to buy a Funhouse playfield for a restore.
