body corrosion near rear bumper repair advice sought
Yahoo Message Number: 105180
The aluminum body of our 82 is somewhat corroded away where it meets the rear bumper near where the ladder attatches. Last year I taped over it with foil tape which held up for about a year then the tape broke in the seam likely from vibration.

This time I'm thinking of using eternabond to cover the seam and corrosion. My ladder was broken so I removed and repaired it then mounted the bottom to the bumper rather than the coach wall which makes more sense to me.

Here is a picture of the corrosion: http://www.flickr.com/photos/safoocat/3849056665/ You can see where the ladder was mounted and the new mount location.
Of course I'm going to caulk that area prior to whatever I put on it.
I have also considered a thin strip of wood to cover the whole thing side to side, fastened on top but covering to the bumper floor.

Any suggestions would be welcome.

Michelle,
 If I were you, I would cut away and discard the corroded aluminum.  Then I would insert one continuously sheet of new aluminum behind the existing and extend it down.  I would have to first removed the bolts holding the bumper.

Good luck,

Sam

Hello Michelle:
 The head of the bolts you see on the flange, are bolts that go through a 2" x 4" that is behind the bumper. Given the extent of the corrosion to the aluminum, there is a very good chance the wood is rotten to the point of needing replacing.
If it's in the budget, a good automobile body shop could probably handle the repair for you.
It will cost you nothing to at least get an estimate. While there, ask them just how they propose to repair the damage. If nothing else, you'll get a professional opinion of how to go about the repair.

Best of luck:

Ed
