I have never had a leak but my unit is only 18 months old and the one taped seam on the outside of my large slideout roof is just starting to lift slightly so as a bit of PM ( preventive maintenance) I thought I would cover this seam with eternabond.
Also when traveling, if I ever tear the roof with a low hanging branch, I could do a repair myself. I am glad this question was asked and I look forward to more reasons why this tape seems so popular.
