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.

SilverMK2 I appreciate that idea, and may consider it for the future if i ever decide to try and restore all of the interior i just switched with my parts car, but for now I am searching for a solution I can use by myself. Sorry, I should have mentioned something about that in my first post.

dannoxyz- so after cleaning the cracks up and sanding down the raised edges, would it work to fill the cracks with the polyurethane glue, and then cover with padded dash filler?
something like this?:

Also, do you have any experience with using plastic welding to fill in the dash cracks? Does anyone else have any experience or preference with using plastic welding? It seems like either polyurethane glue or plastic weld to fill the cracks and then covering with padded dash filler, sanding, and painting is going to be the best DIY solution for me here. However, I don't have any experience with using plastic welding or polyurethane for repairing anything.

I've read mixed reviews about those, SilverMk2. I've heard multiple cases and I think I even read a couple threads on here where the dash cap ends up lifting off the dashboard after a year or a few years... do you have any experience with them lifting off? If it was the dash I'm switching with my parts car, and it's grand canyon of cracks, I think that might be the only realistic solution actually. But the one that's going in doesn't have too many cracks, and it already has a brand new dash carpet that looks nice on it, I was just hoping to fill them in though so it doesn't feel like i'm sweeping dirt under the rug lol.
