Best solution for repairing dashboard cracks and how to finish?

I've been researching what I need to do to finish repairing my dashboard, and with all of the different ideas i've read about I'm really not sure what the best solution will be for my '82 celica supra dash. I'm trying to figure out what the best material will be for filling the cracks and what the best process for finishing will be.

So far it seems like the two most popular methods for filling the dash cracks are some type of silicone filling or a type of flexible epoxy filling. I'm thinking the flexible epoxy is probably going to be the better choice, but maybe i'm wrong? Or is there a different filler material that would work even better on these old supra dashboards? Is there any specific brands that you recommend? Something local possibly?

The other decision i'm stuck on is what to do for texturing and finishing the dash? Both painting and frocking the dashboards seems to produce a decent end result, however I don't have any experience with either of these processes for interior restoration. Can anyone give me any advice for either of these? Do they both usually produce a nice result, or is one method normally better than the other? Is there any other way to finish the dash so it will look good?

Please let me know what you guys think. I appreciate any and all input.

1. Here's one method I used on my Porsche with good results:

2. Silicone is too soft and epoxy too hard. Polyurethane glue has just right amount of give to match. I like Loctite PL line of construction adhesives from Home Depot. Excellent adhesion with flexible-joint. Apply with pointy tip then smooth with plastic spatula. I've used it to repair broken motorcycle fairings, glue tile on walls, attach hard-wood panels to floor, etc.

3. After patching cracks, layer of paint can tie it all together. I like satin polyurethane paint as it's flexible and won't crack like lacquers or enamels. Can even add plasticizer to make it even more flexible if you want. This is common additive for painting bumper-covers.
