I am ashamed to admit, but I am sometimes too lazy for a Supra
Just scuffed the surface lightly to make sure there's no leftover glue lumps from the stick-on vinyl the previous owner put on.
It's not self adhesive. It's a fabric. I could've made a pair of bras out of it but my wife didn't think it's a good idea.
Basically, you spray 3M spraycan glue on the flat surface and use rubber roller to flatten it. Once it grips on a good flat surface then comes the time to contour it to the tricky concave surfaces. Superglue would help alot here, as the 3M had difficulty in gripping the fabric when it's stretched. On the other hand, convex surfaces would be much easier.
Overall I used about 1yd or even less. But I still have the centre console and the powerwindow panel on the driver's door to do (bugger if I know how to remove this one).
Got a praise from a Japanese Nismo mechanic yesterday. It means a lot
P.S.
Yes the area around keyhole is a separate piece. Just wrap the main sheet around it and cut a circular hole around the perimeter using a good hobby knife. Then cut a (approx) 14-16 cm circular piece and use it to wrap around the keyhole mound, starting with the longest side. You'll want to make some sort of conical shape. Once it grips on a section, it's a matter of slowly working your way around the mound. Some cutting and loud swearing may be necessary.
