I used some new screws to hold down my motor cover and they were slightly longer than the previous ones. Due to the longer screws, I put a hole in my exhaust. Now I have water coming in the hole. Note - I do realize this was a very stupid thing to do.

What can I use to patch the exhaust. It's a small hole, less than 1/4".

Thanks!!

Or :rolleyes: lay a little piece of fiberglass clothe over it and do a couple coats or resin with a throw away paint brush, let the resin dry between coats.

3M/1 qt. Bondo-Hair filler with long strand chopped fiberglass Part Number: 762 $13.99 at Autozone. You will need to sand a 1" diameter area around the hole with at least 80 grit paper (36 grit would be better). Wipe the area with thinner or alcohol for good adheasion. If your not concerned with finish then don’t worry about recessing from the original service as you can build up with an 1/8 “ material. Follow the mixing instructions and you will get a good structural seal. That’s a quick down and get’er done method.

Thanks for the advice. I'll probably try the Bondo route, sounds the easiest. I'll let you know how it pans out.

I JB welded one of mine once. Small hole and lasted up until I sold it. Quick and easy fix.

I imagine this thread is so old no one cares but I just used aluminum tape and have run my 92 maristar all summer; no leaks, no issues (so far and i figure ill keep running it like till the patch fails). Found the tape in the attic from the heat pump install in my attic last Jan. Cost was only about 5 minutes of my time.
