The last part was restoring the leather on the steering wheel - I used Leatherique's kit for that - it was very time consuming with adding filler, multiple steps of sanding and finally 4 coats of dye / filler and then top coat finish. The first pic is before, it really looked worse in person than what shows here, then after.
The top coat / last step leaves it a little bit shiny but that dulls after a few days back to what it should look like.
Now the A/C is charged and working, no leaks anywhere, all the rattles (inside) fixed, new NAV unit and all the leather restored!
