Hmm... Question 2: What about "bowl" shaped warps- where the label is in contact with the center of the platter and the edge is 1/8" to 3/16" up in the air (sometimes all the way around?). Those are impossible- and won't adhere to any platter.
I've seen circumferential rings that help with that- but $1800?
(yeah... I know... trash the "bowl" and buy a new copy...)
