I used the EternaBond brand stuff... not sure if there is a specific "roof seal" fromthat company that is different from just plain ole' EternaBond.
I thought it would have been compatible with the bubble material too! I cleaned everything very thoroughly... had to be careful with the acetone on that bubble material as it started to slightly dissolve it when wiping it with a rag. I assumed that it was "really" cleaning it beyond the surface.
I think I need to do something about the appearance. The tube-pooky seals it so there are no leaks, but it look awful... I am selling the camper and I have to explain the situation when possible buyers question it.
