Quoted from High_End_Pins:If you have to wait ten months or even ten weeks you are not using the right product for the application.
For a playfield a product that is installable in 2 weeks is appropriate.
If it is not then it’s the wrong product.
Hardening takes place in a short window. Say 4-8 hours. Curing takes place in a longer period. It can be 2-4 months depending on many factors such as hardner,climate,application thickness and even humidity.
Most manufacturers of these coating materials say wait six months before waxing to insure you don’t seal a surface before full cure but that is because they are factoring in worst case scenarios and potential unknowns to be in the safe side for warranty concerns.
If a finish is no good that is instant. It might become evident in an hour,a week or six months.
No amount of cure time past true hardening or waiting through that two week window will change that. If the finish is appropriate for its intended use it will perform properly as intended. If not it just won’t.
I hate to keep going on and on here .I don’t really care about JJP playfields at all but I know about coatings and playfields in general and there is just so much misinformation when it comes to the subject when it comes to pinball that it can be tough to keep my knowledge on the subject to myself.
I can only assume the clearcoat process on GnR is the same used for Mirco's repro playfields. I don't remember the exact time, but it was in the vicinity of 6 months cured before I attempted re-population of my Micro repro and the clear coat was still soft. Mirco refused to acknowledge the issue. Doesn't give much reassurance from a JJP perspective.
