well when I talked to Frank the other night, he said he used a bondo method, using plastic filler.... I did almost the same with mine, and you will lose your original grain, but with mine I used a padded dash filler... which stays flexible.... I reccomend that way as the heat and sun have started to play a role in the expansion and contraction.... if I would have spent a little more time on it, it probablly would have been better... but I am getting a new dash.
by the way great job Frank.... even though I have already told you
