More News on C6 Painted Tops.

At the NCM Labor Day celebration in Bowling Green, Tom Hill stated that all the 2005 and 2006 painted tops are going to be replaced. The glue/foam is merely a band-aid.

The problem is that the top skin is polycarbonate and not the SMC fiberglass used on the fenders, hood, etc. Apparently it's coefficient of expansion under heat is much greater than expected. When the top gets hot (and this has been the hottest summer for a long time), the polycarbonate material expands. The magnesium frame does not -- and that breaks the glue bond.

Tom says you have three indications of problem:

1. The creaking, popping sound

2. A partial separation of the skin from the frame and resulting wind noise as the wind finds its way under the top skin and

3. the top skin blows off leaving you a frame and headliner.

The fix they came up with was to replace the top film with SMC material, the same as fenders, etc. This plastic has a much lower heat expansion property. They fixed this just as the 2007s were rolling off. The recall (when it comes) will affect all 2005-6 painted tops whether or not you've had the quick fix.

Two problems ensue:

1. The removable top supplier in Vermont has to ramp up to make 40,000 unexpected tops and

2. the weight of the top will go up by three pounds. They used the poly material in the first place to reduce weight. Unexpected consequences.

The dealer will receive an unpainted top for your car and will paint it locally with the same paint and process the Vermont factory uses. Should be OK. The tops aren't painted in Bowling Green anyhow so there's no new "paint match" issues introduced.
