Spooky's playfield durability and clearcoat is up there with the best in the world. My RZ playfield was flawless and I haven't heard of any issues with them. I call absolute bullshit on the sellers claim "i dont know what to expect on clearcoat issues with spooky, it may be common."
I'm guessing he did something stupid to cause the damage, and he deliberately hid that when selling. Very shady.
