@vid1900, so here's my Future Spa. According to the person I purchased this from, the playfield was a "NOS Assembly," meaning the playfield was swapped with a completely new assembled playfield with mechanicals and plastics. It does look great.
There isn't 40 years of chemicals and wax and ball trails in it, which is great. However, I've noticed the inserts are cupped, and the surface of the playfield seems to have some ribbing of the wood grain showing, which I assume is normal.
Right now, my plan is to wax it properly and play on it a while, but I will be restoring the cabinet next year. Since the paint is pretty much perfect, do you recommend a clear coat process for this playfield before we play on it too much?
