fibreglassing over vacuum formed vinyls

Was your question answered?

Can he just fiberglass over the existing vinyl with padding? Some of your older cars have 3" thick pre-formed foam pads.  Just wondering.

I wouldnt advise f/g over the vinyl permanently ,but you could make a mold of your project with the vinyl still attached to it, then remove the factory piece and replace it with the f/g piece.-A vision without a plan is just a hallucination-

how about if i remove the vinyl and take it back to the stock formed plastic? could i then use a bondo:resin mixture to cover then paint the dash?

You could do that if you wanted ,I would recomend scuffing the plastic up before applying mix.Use some 36-80 grit paper and leave some nice scratches in it so the bondo/resin mix can really adhere.It would be more beneficial and faster if you just scratched the plastic up lay some f/g down on it ,scuff that the same way as the plastic , do one more layer of mat and f/g then scuff and do bondo resin mix.-A vision without a plan is just a hallucination-
