Eternabond over Dicor

Yes, go for it. Good long term fix for that area. Still need to look at it once in a while but will holed up much better in the long run.

when you roll it down it will mold to whatever is under it

Motorhome is only a year old so the Dicor is in good shape. It just has some lumps where they applied extra material over screw heads. Was thinking of adding Eternabond more as a preventative measure rather than having to continually maintain the Dicor.

If the dicor looks that bad that it needs eternabond tape maybe it should be scraped off. I just remove loose stuff and put dicor over other dicor. If I have real bad areas like where my front cap or rear cap attaches I removed dicor and used eternabond tape. It is a judgement call.
