Wrapped Dash Piece
Start by joining the pieces together. My method was pretty simple:
1. Place some foil behind the seam on the dash.
2. Install the left dash piece.
3. Mix some plastic epoxy and apply to the side.
4. Install the right piece.
5. Apply some more epoxy within the gap.
6. Wait to dry and remove.
I glued it in the car since it seemed like they didn't line up in the car. I wanted the clips to match... So my method was to glue it in the car, then make corrections afterwards.
After some filler and sanding.. good to go.
One piece Cover
I decided not to use a multipiece with a french seam. Using a single aesthetic stitch on a single piece was MUCH easier.
I always make a template. This is my method:
1. Use masking tape to cover the desired area.
2. Draw where you want your stitching (or seam for a multi-peace with french seam)
3. Carefully remove the tape and lay flat on a piece of poster-board.
4. Cut the poster-board to shape.
5. Fine tune if needed.. sometimes you add some tape to the 1st template to remake a better one.
Since this is only one top stitch.. I needed a reference line. I tape the template down, then use tape around the perimeter for my line.
I then sew around the tape line. (the finished part you see below was Trial #1. I was not happy with my original template so I remade using this method).
I usually sew top stitches by hand by turning the wheel. My machine is very aggressive and makes jagged lines with the foot pedal. If you look closely, you can see where the stitches meet at the bottom left corner of the dash piece.
Halfway glued with the Dap Weldwood HHR. I didn't glue the center section at all. I feared the glue would show bumpiness. So it is merely stretched and glued from the stitch to the back.
Leave about 5-10mm overhand around the edges, apply glue, and wrap.
The center cutout takes patience, heat, and strategy.
DONE!
