Great news for you builders that bought my gauges and have
gotten sticky fingers epoxy on the bubble during some phase of
assembling and installing them, which is not hard to do. Up 'till
now you were stuck with the goof.
But Nick Ugolini has graciously run a series of several tests on
the bubble material I sent him using 3M General Purpose
Adhesive Cleaner .... With GREAT results.
The bubble material is made out of P.E.T.G...
Nick is planning to publish all the results with different cure
times, and different epoxys (with pictures) for the builders.
Thank you NICK !
