Eternabond is NOT all some make it out to be. I did what the factory called a "picture perfect" installation yet the roof still leaked. I was lucky that they replaced it under warranty. I will NEVER use it again...on my first 3 TT's and 250K miles never a leak with Dicor routine maint. It is also a bear to remove without destroying the roofing. JMHO
Wouldn't it be cool if they had a caulking tape strip that you could lay down over screws and everything uneven and use a heat gun and make it flow down and around all the uneven items? The edges would look straight and the sunlight would not affect it.
On our Bigfoot which has a fiberglass roof, they used a combination seal. The fixtures are all imbeded in eternabond/butyl caulk and then that is covered by dicor. What I have done a couple of times that repair is needed and solar panel installation is to put a blue masking tape square around the area to be sealed, embed the part with a liberal coating of butyl caulk, let it dry a couple of days then clean it up and put a finish coating of dicor on top. After another couple of days to let it all harden a little I pull the tape and get a nice looking seal. The dicor does seem to need to be repaired a little yearly - ie fill the cracks.
How about if you had to remove it-how hard is it to remove
Why would you need to remove it?
Say a skylight or vent breaks or you just want to update.
Right. I think they recommend just cutting it and leaving it be, but I'd probably try getting it off first. I'd approach it the same way I do Dicor and Pro-Flex. Heat gun, nylon body tools/scrapers, and naptha.
