View Full Version : cutting out rust spot over wheel well

04-14-2008, 12:58 PM
i have rust spots growing above the rear wheel wells on my '93 Grand Am GT. wondering if its better to cut out pieces from the junk yard and weld them in place, or just use bondo? please help.

your car is not a 1993. it looks to be a 1999-2006

If you do not know how to weld, I would take it to a body shop.

Bondo NO

Replacing the rear fender is no easy task. Unless you have some good bodywork exp.

I'm getting the rust too. It's juust starting to become visible on the side, any idea how much I'd be looking at to get this repaired?

couple hundo at least

if you have paint maybe less.

that sux man..i hate rust.

if it's just surface rust, you can sand it off and apply rust converter then sand and apply a coat of primer and paint.

i dread the day i find rust on my GA. That's why i wash and wax almost every week in the summer time. And spray down the salt every week in the winter time.

Thank God I don't have to deal w/ that sh!t here in the South.

Unless I live by the beach... J/K...

and yeah, i miss the south. rust is cancer

I've got that problem with my '97 grand prix. There's a spot completely rusted thru right under the gas door, and one starting on the other rear fender. The car is originally from MI of course. I'm going to try cutting and welding in a new sheet metal patch and getting the rear quarters painted.

If the patches are small enough, can you just cut it out, use aluminum tape and bondo the darn thing?

I wouldn't. Stuff that's bondo'd to sheet metal tends to crack and come off eventually. It needs to be welded to make it permanent.

Would spraying a rust inhibitor on the areas that the cut has been made, help keep any new stuff from spreading?

Is there a doctor in the house?

Bondo anything that you care about what it looks like, and you need NOS stickers all over your car.

Not to be mean, but take it to someone. If you've never done this before your not going to have an easy time with it.

yeah, but for a poor college kid, taking it to the shop qould be expensive, especially if i already have all the tools. ive seen plenty of bondo jobs gone wrong, i think i'll steer clear.

i will keep posting, i'm cutting the rust out tomorrow,

wanna wish me luck?

04-14-2008, 10:30 PM
yah good luck. and just a suggestion, be sure to make pleny of templates before and after u cut it out to make sure it it a perfect replacement. and have fun with all of that grinding and sanding.
and any chance of before and after pictures?

04-14-2008, 10:32 PM
i wanna up my small post count so yea..... Good luck.

04-14-2008, 11:24 PM
yeah, i got some juicy before pics to post. those are always interesting, haha

If i had spare body panels around and the tools, I would practice. Sounds like fun though. I would put together the funkiest kit for ma car.

change of plans...I've decided that since the part i need to repair isn't on a flex area, that I'll just make a backing for the cut-out and just bondo the thing. it will crack in a couple of years, but not as soon as if it were on a door or other metal surfaces that tend to bend or shift slightly. this gives me time to save dough and pay a pro to do it right.
