RV Repairs electrolysis, I have been in the market for a class A motorhome, diesel pusher for awhile. I have found a excellent candidate that would meet most of my demands. It is a very low milage 2001 Harney Coach with double slides and only 16,000 miles on a 300hp cat engine. The only problems are a few minor bubbles and pin holes on the drivers side. The seller claims it is not delamination but, it is electrolyisis. Is this a major problem and can it be fixed fairly reasonably? I hace seen photos, a few pin holes and a couple of bubbles about 6" in circum. The pin holes look like there is a screw under the fiberglass that is colored and causing a small hole. Should I stay away from this or what?
