'89 560SL - Fuel Tank Punctured by Screw

[dsutton01]

I had a couple audio amplifiers installed in my 560sl recently, and noticed immediately after i got the car back that there was a strong fuel odor in the trunk and cabin. I didn't think even consider that it may have been related to the installer - I just assumed it was my gas cap, since when i removed it, i could see wet spots on the rubber seal, so i bought a new one and installed it, but it didn't fix the problem.

After reading thru a bunch of posts on the forum today, i decided to remove the vertical metal panel in the trunk. Of course, i had to remove the long sheetmetal screws the installer used to fasten the amplifiers onto the panel...

As soon as I got the panel off, i noticed the small puncture hole in the tank from the installer's screw. the horizontal foam strip running along the fuel tank was saturated with gas, and there were drip marks along the side of the tank (no wonder it smelled much more strongly after I put $30 in the tank yesterday...).

So now i have to patch this very small screw hole. What's the best thing to use to patch it? I was thinking epoxy would work, but perhaps there's something better?

Any help is appreciated.

thanks.
