The trunk is now all welded together. Tomorrow I'll paint and seal it, then I'll be able to start building the hood framing.  I left some extra height on the trunk lip. I'll be able to trim this down to account for the hood height, the hood framing, the fiberglass that will encapsulate the hood framing and the trunk seal.

Just finished painting the trunk. I'll have to wait until tomorrow to get everything sealed.

I decided to finally get to some fiberglassing today. I started by creating a foam mold for the upper part of the air conveyor for the driver's side main vent. I'm using a standard 2 part polyester resin and 1.5 oz mat fiberglass. After getting everything setup, measured and mixed, I went ahead and glassed two layers of mat. Now for the bad part. It's been two hours and the resin still hasn't gelled.  I was very careful on my measurements, the temperature in the garage is ideal, yet nothing!  I've never had this happen with any resins that I've used in the past. If it takes much longer, I'm just going to pull all the wet fiberglass off and discard it. First time I've used this brand of resin...may be the last!

Turns out this resin has a thin film set time of 3 hours at 78°F. I think that was actually one of the reasons I had bought this one instead of the type I normally get. I guess I had forgotten that.  I'll see if I'm happy with the result when it finally cures.

The top part of the air conveyor is almost complete. I'll need to trim once it's finished curing. Still need to perfect my fiberglassing technique. I haven't glassed any parts in quite a few years, but so far I'm happy with how it is turning out. I have about a dozen air conveyors to build (which are all hidden from view)...so I'll get lots of practice before I start into the visible parts...  Ok...I probably won't get to all these up front...

Trimmed the top air conveyor fiberglass cap. Second pic shows it in place under the fender.

When I made the top of the air conveyor, I simply made a female foam mold, covered it with a thin sheet of plastic and layed up the fiberglass. This worked fine for the top of the conveyor because of the location, but I'm going to switch up my technique and start building plugs, and then use those to produce molds. A lot more effort involved, but I'm hoping the end result will be much better. The two pics below show the next foam plug in place, supporting the grill, and creating the expanding opening of the vent. I've cut the main door opening panel back a little. I've opted to have a tight curvature for the opening to match the grill width, rather than bringing the panel to the grill width with a gradual curvature. This helps deal with the "Fiero" parts behind the panel, especially the gas fill line (which I've now elected to move to the passenger side, the same as on the real Aventador.). The bottom of the plug curves down to the bottom of the radiator. The plug will be finished with body filler, sanded and primed with a high build primer.

Another view of the plug in place.
I've spent a little bit of time adding body filler and sanding the surface smooth. I just finished it up with three coats of high build primer. I'm letting that set for a while, then I'll finish sanding it, polishing, waxing, etc and make the mold. Good thing I only have about 40 or so parts to make....
While waiting for the paint to dry, I reinstalled the trunk. Fits perfectly. ...a little bit cleaner than everything around it... 
I also started installing the hood hinges. I've drilled some flat plates for the hinges and welded them at one end to a support. Once I'm happy with the hinges I'll build up bracing for the plates to hold everything securely.
...Unfortunately, nothing ever goes smoothly. After getting the hinge plates put in place and installing both the hinges I found that I couldn't seem to get them aligned throughout their travel. They seemed to move completely differently and ended up in different locations.  I tried adjusting them, but this didn't help. Finally took them off and noticed that their linkages are completely different lengths. This sucks since these are OEM Lamborghini hinges that I ordered from Europe. Turns out they sent me a wrong hinge. Now I'm going to have to wait a while for a replacement.
