I am giving some serious thought of molding my scoop sail panels in the car. Currently I have mine riveted into place and painted over. I did not trust any tape to hold these in place. I believe it would look better this way. I can not seem to find any discussions this. Does anyone have any experience or thoughts about doing this or not?

Here are the scoops:

No real experience, but no... I wouldn't.

But that's just me. YMMV.

There a particular reason why you wouldn't?

Fiero quarter windows are held in place with 3M tape so why would they not work in your application? After a recent install, a month later I drove my Fiero over 100 mph and they held firmly in place. The key is to use the correct 3M tape. If you are interested in doing it this way I'll look up the part number for you.

I understand that 3M tape is used, however I did not want to mess with it or take the risk of it not working like many others have had happen. Additionally the fiberglass panels I am using are not as flexible as the stock windows and I do not think the 3M would hold them in place.

I am simply looking at a more permanent solution that also gets rid of the lines to bring it all together.

Georgia Fieros had a fastback with similar quarter windows. Made of fiberglass. They were bonded or taped on and have been on the car since the early 90's. I just looked at a very closeup picture and there were no screws or fasteners of any type, so I don't know which method was used. When we had the car, there was no bonding agent visible around the mating areas.

But, like Raydar, I just wouldn't do it. If they were ever damaged for any reason, it would probably be difficult to remove or repair.

You will be faced with the challenge of bonding together different materials; Fiberglass and Urethane. Both the fiberglass and urethane fillers are different chemically and I don't have enough info to provide on using them to bond dissimilar materials.
As for the 3M tape if applied correctly and cured at the right temperatures it provides an extremely strong bond. Once it sets the only way to break the bond is to cut it with a piano wire with two end handles.
Of course it's your car and the decision is yours alone, so do what you feel is best.
For the curious on this thread the quarter window application tape is 3M part number 06450 1/8" thick by 1/2" Wide. Its a Urethane double coated tape.

It has been done a few times, but for me is just doesn't look right without the transition between surfaces.
You could bond/fiberglass in some attachment studs to the backside of the quarter window and use those for a more positive attachment and keep the smooth look on the face.

And, like Raydar said about the scoops, I wouldn't mold them in. You would lose the graceful line from the top of the window down to the rear deck.

I will look into doing that. Glassing in a decklid hood scoop right now. So I am at least getting my fill with fiberglass work.
