Is there a material or product that can harden your carbon?  I purchased an older set of HED wheels this past summer and they are more like a flaring than hard like the wheels I am seeing in the LBS's. 

Just wondering if there is a product that I could use to harden the wheels up.  I have some conditioner for the wheels but it doesn't really do anything other than clean them.

Many of the older carbon wheels were just built that way.  Never heard of any way to "stiffen" carbon.

Don't worry about it; that's the way the Hed wheels are made.  A fairing bonded onto an aluminium rim as opposed to a wheel like a Zipp that is a structural carbon rim.

Just apply an HTFU decal to your wheels.  The more miles you put on, the harder they'll be.  Honest.

The answer to your question is no. Are these used wheels? if so, Have they been in any wrecks or crashes? Have you had them inspected by an expert? Do you know the original owner? Once a carbon composite (not sure it that's the correct word) cracks or delaminates there isn't anyting you can do to fix it, they need to be replaced. That's why you need to be really cautious when purchasing any used carbon item.

Feel free to correct me anyone, If I'm wrong. THx.

If the carbon was structural then you would be correct.  However, in the Hed wheels, the carbon is simply a fairing and if you push on the fairing it feels fairly pliable.

depends on the wheel;-)

the jets (not sure about older) are just a fairing
the stingers (i think) are solid
If you have a floppy H3, you're screwed;-)

True, I was assuming based on the fairing comment in the OP. If it is structural carbon, it is time to toss the wheel.

Kind of off-subject, but if you can do a carbon fairing and plastic wheelcovers, why not make plastic 80mm fairings? I know they won't last as long,but are there other problems with this?

Solid with a foam core I believe.

Unless your H3 is a H3D, which is a H3 with a flexible fairing.

A whole lot of confusion in this thread...

A fairing is supposed to be flexible... that's that whole point of it. It allows you to take a strong, durable box rim and give it the aerodynamic benefits without adding lots of weight. And many of the best wheels are built this way, HED, Mavic, etc.

"Solid" carbon wheels are all built around a foam core.

For HED this is how they are made:
HED Jet, box rim with fairing (clinchers only)
HED Stinger, solid (tubular only)
HED Alps solid made in sections, same rim as HED3 (both clinchers and tubulars with aluminum brake track)
HED3, solid made in sections and fused (both clincher and tubulars with aluminum brake track or tubulars with carbon brake track).
