I wondered about the thin parts, too -- but I think it should be okay. I'd probably try casting before I'd be willing to destroy a fascia -- not to mention my 3D modeling skills aren't great, so this would be the quicker solution in the long run.

On the plus side, if you're building a mold, you can also get an impression of your dash where the fascia will sit, and get an exact fit.


And while things dry, you can work on the 3D model... try both, and see which works best. smile
