Thanks for the sympathies. It's a real shame, I haven't seen too many necks that impressed me the way this one did and it just feels like a loss.
The tape I used is regular ol' blue 3M painter's masking tape. It's the same stuff, same roll even, that I've used on numerous bodies and necks, Warmoth and other. I've certainly never experienced anything like this with it. And it wasn't even on for very long, 45 minutes to an hour tops? About half of a Lars Larson podcast...
The finish is clear gloss, and as I understand it all of their gloss finishes are Poly? Beyond that I wouldn't know how to distinguish between the two. The spec sheet is not specific in that regard, stating only "Clear Gloss".
I sent those same pictures off to Warmoth with an e-mail saying what I did and what I experienced, not sure what to expect but I'll keep this updated.
Simply to indulge my own curiosity, not that any part of me is hoping-against-hope or anything, but is a repair of this kind of damage possible? I can't help but think this neck is worth saving if it's feasible....
