I currently have a 2002 cab over that has been a very extensive project. I purchased the camper a few years ago with known water damage. I have repaired all the water damage and my wife and I have updated the interior of the camper. I am now in the final stages of cleaning and updating the look of the exterior of the camper.
The previous owner's did not care for the camper like one should. The owner I bought the camper from at some point realized there was water damage and put an insane amount of silicone caulking over every spot he thought leaked or could leak. I have spent hours removing the caulking and sealing the corners and windows as it should be done. At this point the exterior of the camper is water tight except for two spots large spots (4"x4") and some smaller pin hole. the larger spots are on the rear of the camper and are very visible. These holes are from water getting on the inside of the camper skin and rusting through the metal. This is my 4th Alaskan and I have never seen this happen.
This brings us to my question. How should I patch/seal the camper. Because these spots are on the side of the camper I want it to look good. I will be putting new skin on the exterior of the camper, but not for a few awhile. I need to save my money for a larger truck, but will skin the camper when finances allow.
So... my current idea is to patch the holes with Eternabond. It looks like a good product for areas you can't see, like a roof. I am a little worried it wont look so great at eye level. Any other ideas or thoughts?
