I tried a full dash cap and didn't like the way it fit so I got the half cap. Only problem was it didn't hide the damage to the lower part of the dash. This took many hours and a whole lot of back pain. I used marine grade vinyl. I found out after a few tries that it would stretch around curves and corners by using a heat gun. Gluing, wrapping every few inches and waiting for the glue to dry before moving on. It would have been much easier to do it before putting on the cap and easier still with the dash out of the car. I also found that a soldering iron would weld it to the dash on the corners of the vents and gauges.

 

I need a full writeup of this.. MAybe it's too early for me, but I think everyone would appreciate details on restoring our cracked dashes. Now that I look at the picture it makes a bit more sense. So that is a half cap with the vinyl on the bottom half of the dash?
Supposed you did the whole dash with marine vinyl?

 

There are a few threads on ClassicZCars.com on repairing cracked dashes.

 

I already covered a full dash cap with a carbon fiber /vinyl material. I didn't like the way the cap fit so I tossed it. The marine grade vinyl can be had at fabric houses or on ebay. I would not be afraid to do an entire dash IF it was on a bench. The vinyl or carbon fiber cloth can be heated and stretched about 200%. The hardest part is pulling it around corners into the vent and gauge openings. It is important to use a surgical type knife so you can overlap the scrunched up areas and slice through them to butt the edges together. Last I heard it was $1200 to have it recovered. I already have the material to do my next car in a red/black carbon fiber cloth. The theme will be throughout the interior, should look good.
