I've noticed this on a few Bonnevilles and was wondering if any one else had the problem of a rusty gas door. It wasnt bad until a year ago.

Mine was terrible! I bought a new one from gmpartsdiect.com, primered, painted, and clearcoated it. Here is a pic from summer, 2005:



It was MUCH worse when I finally swapped it out a couple weeks ago. The rust was streaking down the fender from the rain.

Moving to Appearance...

Wierd, I didn't have a spec of rust on the gas door on my 94...

What'* even weirder is that I have the same year and not one speck of rust on my car.

It must be a 96-99 thing. I have only seen one 92-95 with rust like that on the fuel door.

Yeah there wasn't a spec on my 94 either. Wonder if the rusting gas door had something to do with a batch with a bad batch of alloy or something...

I enjoy zero rust. Oregon doesn't use salt for ice. We use either a liquid chemical de-icer or gravel (similar to the red stuff on a baseball infield).

Unfortunately, the fine gravel causes roadrash, but I've recently repainted my rockers on the Zilla to fix that.

Yeah, same with Alberta. Although they over-gravel everything, resulting in awful pitted windows, chipped front ends, and those damn rockers. Even w/ mudflaps I couldn't stop the rocker damage, just learned to live with it. Although I was contemplating applying some of that clear 3M stuff after a repaint.

I gotta find the can, but I put a chipcoat on my rockers over the paint the last time I painted them and it'* holding up REALLY well. It'* intersting, because if you look at Bone-Evil and Silverbullet, one has it already, and the other doesn't. Even though they're both Canadian 2000 SSEi'*.

Interesting.. the rusty gas tank door seems more common than other parts of the car in certain areas.

While they use a calcium for snow removal in my area.. I don't see how salt would be in such a concentration on the door versus the fenderwell. Either way.. There are some choices out there for replacement and the door is only held in by a couple of 10mm nuts after you move a couple of 7mm bolts.
