Craggy

I'd like to ask if the lacquer used on 2019 Gold Tops is check proof? I ask as I've tried to induce lacquer checking with the hairdryer /compressed air method, and it's just resisting it totally. I notice the finish is very soft, easily picks up scratches, is that because it hasn't cured maybe?

Would a full batwing scratch plate easily fit onto a '61 SG?
