First, some trimming warez - scissors, trimming knife, brush and 450ml of contact adhesive thinned with a 10% mix of glue thinner.
Vinyl cut roughly to shape:
Parts all covered in contact adhesive (including the vinyl, not pictured):
I left the glue for an hour, then added a second layer, which I left to go off for half an hour.
I started by deciding where to apply the vinyl first, which was across the middle of the build. This is the flattest area. Dips we can live with because the vinyl with stretch (e.g the arm rest area), but bumps are a PITA. If you use an area with a bump as your base line, then anywhere that isn't raised as high will involve trying to make the vinyl narrower, which isn't easy. So I went across the middle of the build, just to the top of the ring over the speaker.
Then I started smoothing it out over the front of the build:
Up the rear of the door. Note that I'm concentrating on the areas that are most commonly and easily visible first. I've also depressed the vinyl in to the ridge - this ridge marks the point where our new vinyl is going to meet the OEM padded vinyl, so it's here that we need to cut.
Trimming knives are perfect for this job.. the plastic ball allows you to run the knife along the vinyl without damaging it. The blade is in the C shaped section:

Trim excess material with a scalpel:
Work the vinyl in to the ridge. I wasn't too impressed with the cotton sticking to the exposed contact adhesive, so I ended up swapping to use keys after a while:
Now for the OEM light cover:

And the arm rest:
Whoops.. I've cut a little too far. I ended up pulling the vinyl up and angling it down a bit - this worked out very well:
Now let's start on the dash end:
The bottom front end of the door - this was always going to be the hardest part. The key here is to work slowly, and don't be afraid to pull the vinyl up and start a part again.

Remember, work down the side very slowly.. down 1 or 2 mm at a time, working around the edge in stages where necessary
Now let's get the rest of the edge sorted:
Now for the other bottom edge:

Apply contact adhesive to the rear, where there's vinyl to stick down:
Stick down the rear of the speaker trim ring and arm rest:
Now sort out the edges:

Hot glue the grille in place:
Araldite the original plastic rivets back to help hold the various bits in place. This was done in addition to a number of random screws through some of the various rivet holes:
And the finished article:
When it arrives, I'll be removing the grilles and placing some grille cloth over the grilles, so the drivers and dynamat are hidden.
On to Part 5 - The Pocket Backs
