Here is where I am at, with making my spoiler fit.
Basic Rundown is.
1. Made a FG mold of the trunk.
2. Sat spoiler on car, marked and drilled holes.
3. Only one or the 3 studs (on each side) is long enough to go through the sheet metal due to the shape. The 2 outter-most on each side got nice long jamming nuts added to the studs. which were cut to size I will then use a 10mm bolt for them.
4. Pop FG mold off trunk. Sit back in place and align spoiler on it.
5. Make a couple alignment marks for repositioning.
6. Grind top off fiberglass and bottom so spoiler with 24 grit roloc discs.
7. Used 2pt SEM's Panel Bond Adhesive to bind the spoiler to the fiberglass.
8. Bolt the spoiler onto the decklid to clamp the 2 halves together. Wait 24hours.
9. Unbolt spoiler. And using tin snips I trimmed the fiberglass mold of the trunk down to size.
10. Using the left over hardened fiberglass I made some wedges to use as the sides of my mold. I then glassed them into place with fresh FG mat.
11. Let cure and then grind with 24grit disc to rough the surface and spoiler sides up. Applied 3M's 2pt ABS Repair structural plastic to the outside embedding the FG sides roughly shaping it to the final contour.
12. sand a repeat step 11.
13. sand.
14. CURRENTLY AT THIS STEP
I will do a bit more sanding then hit is with a 2pt epoxy finishing cream, sand and a very light coat of bodyfiller (to fill any pinholes.) After wards prime, sand, prime, sand and finally paint. (Some where in there I need to finish welding up the holes leftover from the Limited spoiler...)
Total time so far is around 9 hours. Not including waiting for fiberglass and epoxies to dry. This also doesn't include the 2 hours trying to get a nut out after dropping it inside the decklid...
Fiberglass cloth followed by a layer of mat and sealed with cloth. The cloth on the bottom gives it a very smooth finish which will be very nice on the bottom side of our spoiler.
still more sanding
