stuff snipped

i know acetone will fog plexi, and ammonia products can lead to
microfractures.

Perhaps the lacquer thing was a matter of timing.

Don't use alcohol.

This 25 year old backing paper laughed at acetone, alcohol, turpentine, hot
water, ammonia and more. Nothing softened the paper or seemed to penetrate.
I was pretty shocked to see the backing peel away and the Plexi not be
melted by the LT.
