Damn, that's impressive!

You've inspired me to try to tackle the dash on my Corvette. I may have questions tho.

OK, well I got back to the dash project...

I'll share what I learned so far to serve as a warning to others.

So I just used contact cement to attach a bunch of foam pieces. I'm not sure what I could've done better here. It's hard to manage large pieces but in the end seams will show through on the vinyl.

Then I glued more pieces

Then I started sanding it smooth. The optimal tool for this was a portable belt sander followed up with a block sander.

That went pretty smooth. Here's a test fit. At this point I'm not sure if what I plan to do will work.

OK, here's where things stopped going according to plan.

Any time I've worked with vinyl cloth in the past, it was on door panels, amp racks or speaker boxes. Basically, things I could staple. My experience with contact cement has not been good. Maybe now will be different.

So I started with the valley that I knew would be problematic. And it was. The cloth barely held and certainly wouldn't hold the extreme stretching I'd need to do.

So It was time to face reality. I was going to need to have a seam. I watched a couple videos and my daughter has a sewing machine. I ordered some UV resistant #69 thread as recommended online and made my first stitch. I'm not sure what you call this. A French seam is when you run a stitch down both sides of the seam. The video I saw was all in Spanish so I'm calling this style a Mexican seam.

OK, so gluing went sort of as planned.

Here's what I learned:
* It showed every little imperfection underneath. Most people put a thin padding layer here and I'm guessing that's why.
* All the hot-rod shows have the upholstery guys cut a small channel in the foam for the stitch to fit. Now I see why.
* If all the glue feels cured, and you take your nice new dash out to the car and let it sit in the sun, all the glue will come undone. **

I did it in stages. First the front part.

I bungee'd a cloth on the "valley" over night to ensure it wouldn't pull off.

The next day I did the back half. I should've made better plans for the left side of the dash bezel. It was very hard to get this to wrap around all the compound curves. I probably would've preferred to put in another seam.

I think it looks OK. The screw holes underneath look a little weird in the pic. I c-clamped washers to hold the shape for the stock screws. The defroster vents were not as forgiving as I'd hoped. I would've angles them a little more in retrospect. Over all, it still looks better than anything else on my truck so far and it was a good learning experience. I'll probably try to do something similar for the doors because it's a lot cheaper than buying stuff.

Thanks for attending my Ted Talk.

** I panic repaired everything I think. The contact cement I used was Barge and I thinned it a little but so it would go on easier. It's supposed to be fine for this type of application. I'm hoping if I give it a few days to cure this won't be a problem again.

I filled all the speaker holes (and cracks) with fiberglass/bondo and wrapped in leather. btw I like the seam to just be around the gauge bezel not all the way across like some do. just my 2 cents

If I had skill to do this, this makes way more sense. Especially that bezel seam, but that has to be perfect. I may end up getting a chance to try sadly.
