i believe the Rora Suffers from the problem too....I was under the impression that the incorrect primer was used, and that is what caused the Bubbleing

oh ya and like i said im getting the bubbles underneath at 17K, so your 77K is nothing

I'd check with a different shop. The dealer where I took mine trying to get it covered, at least partially, by GM (no luck) quoted a price of $450 to remove the hood, strip it, and repaint it.

Mine was repaired 2 years ago and hasn't come back yet.
and it was for free, so I dought they replaced the hood when doing so.

My 97 Riviera had the same problem and a body shop only charged me $450 for the entire job to fox my bubbling hood. Your dealer doesn't want to fix it because they're lazy.. this is a job that would actually require heavy sanding to make it turn out right.

Thanks for the encouraging news. I surely will do more shopping, and maybe some sanding & priming.

Found another option: a FIBERGLASS HOOD for US$375

Anyone heard anything about this?

didn't know anything about that, I'd say that would be a great alternative "IF" the bubbling ever re-accured. Those who fixed or waiting to see how bad it gets might use this.

I wonder what changed in 04-05 models? says its useful only on 00-03? mine may have already been fixed (please I don't want to go throu this ) what causes this to happen ONLY on the hood? I guess I/we should be thankful for that.

The Primer they used was incorrect, if so I hope I doesn't affect anything else trunk body, Does the heat from the engine contribute to the problem? I mean sertainly there must be certain factors like whats the weather like where you live perhaps?

1993 SLE said his has already started, I can't help but to wonder what triggers this problem and if All suffer at some point?

I dont believe anyone has done a fiberglass swap.
Its what I was thinking if I ever mold on hood scoops.
this one is $280.95 http://cgi.ebay.com/ebaymotors/00-05...mZ330002805230

My 2000 was in a fender bender 15 months ago. My hood with original paint and 60~70k at the time had no blistering. The jy hood I got was blistering pretty bad underneath near the striker plate and was just starting to show a little on top. I took striker plates off & saw pretty bad corrosion on both hoods where the steel was against the aluminum. To stop galvanic corrosion you need to create a dielectric barrier – so I cleaned rust off, primed & painted both surfaces, and then cut a piece of gasket material to bolt in between the 2 parts. On the top surface, the guy who painted it 4 me used an epoxy primer on bad spots. I did not notice corrosion on the hem flange. I am guessing the amount of exposure to weather & road salt plays a significant role. Looks like most of you on this thread are northern exposure guys. Anyone know if this is occurs down south too?

man with a fiberglass hood the possibilities are endless, just think kow easy it would to have hood scoops...
