I had a leak at the spoiler stands, so I took it off, and because the Fiero store gaskets were not as wide as the stands base, I reused the stock ones with some black RTV, The problem is I managed to split the stand at the base from being a Bull in a China Shop!!
How does one install them to the deck lid and have the nuts tight enough, but not so tight the stand cracks, at the base.
I have a set of stands to replace the cracked ones, I just have to paint them, and like to not make the same mistake again..
The ones on the car are holding the spoiler tight,just letting water in from the split, So, I would like to fix the split/crack.
Anyone know what they are made of, and what would be a good bonding agent ? And what type of filler to use to finish them off with?

The rear spoiler is made out of Dupont Bexloy using an unusual 'blow molding' process. It can be glued with methacrylate, which is the stuff you use when your rear-view mirror falls off your windshield. It glues that little stainless button to the glass. It's not cheap, but you can find it in auto-parts stores. I have no idea about the filler....maybe somebody has tried something.

As to the filler I'd suggest using a lot of RTV on the top side of the gasket (some underneath too, but a whole lot on top) then try to clean it up once the wing is in place. I used a little, but it left wide gaps around the base, so I used a tube of sealant left over from doing headlight motors to fill in that space. But that's a very messy job once the wing is in place.

For holding the wing on I fashioned a piece of aluminum and used a sheet metal screw from the underside to grab it. So far so good. It seems like the RTV is doing as much to hold the wing in place as the glued-in nuts. The three remaining nuts sure don't look like they could resist much pulling.

Here's the strap:



I also sealed the underside of the trunk lid. This is the one with the sheet metal screw and aluminum strap:

Per this link, http://fierosails.com/BodyPanels.html the wing stands are made of Thermoplastic Olefin (TPO). A google search will yield several sites with information about TPO repairs, which include plastic welding as well as adhesives.

I gave out some bad information....the wing stands are not Bexloy after all....just the wing part. TPO is difficult to bond, but it can be done. It may be better to find stands from a damaged wing.
