Anyone esle try this?

Im sure I am not the first to have tried this, but after several attempts at trying to salvage my dash pad, I am on my last ditch attempt. I first filled all the cracks with JB Weld, and the sanded theat back down to being flush. Problem there is, that it will still separate and I figured it may happen. Well only one hot night in the garage proved that to be true. So as I said I am on my last idea before I have to break down and get a new one.
Yesterday, in my garage pushing 95 degrees, I decided to apply fiber glass over the pad. This is mainly in an attempt to have one soid surface all the way across, this way it wont crack. Well I let it set up and rough sanded it last night and it actually came out pretty well. I have more sanding and shaping to do But I think it'll work for my daily driver.

Anyhow, has anyone else done this and if so what were your results?
