I know there are several threads on here about Eternabond, but I have a question I can't seem to find the answer to.
A few week ago I installed the 4" wide tape over the front & rear seam of my roof & around the skylights & vents. On the package instructions it suggested that you caulk the leading edge seams to prevent raveling while driving down the highway. Do those of you that have installed this tape also add the caulking to the leading edge? If so what did you use? If not have you seen any lifting of the tape & how long have you had it on the roof?
Has anyone installed this tape over the rain rails or gutters on their RV? If so did you use the 2" tape? If not what did you use to seal this area?
I have no leaks & have not had any, just doing preventive maintenance.

I installed 2 years ago on roof to cap seams. I did NOT caulk the leading edges of either seam and NO problem to date. I did caulk the ends with white Dicor sealant purchased at an RV store.

Used 2" all the way around mine where the fiberglass goes under the gutter rail. No problems so far and didn't use any caulk. I read the same thing but didn't seem like it was needed. Time will tell I guess.

Thanks Ronnie & Wizard for confirming my same thoughts on the caulking. As good as this stuff sticks I have a hard time believing that wind resistance at 65-occasionally hitting 70 down hills would lift this stuff. I think I will get 2 rolls of the 2"x50' and do my rain rails.
We use a metal tape on large jets going 450-500mph & the tape does come up but not very easy & it is by no means as sticky as the eternabond.

They use this on big commercial roofing jobs used it on Caesars AC casino, it's on the beach 150' in the air, usually a steady wind up there I've been up there in 70mph winds didn't see anything lifting

I read somewhere that the biggest reason for caulking the leading edge is to prevent dirt from sticking there and turning black.

That makes sence.

I re-did my entire roof 18 months ago using 4" tape over existing 2" tape as approved by Eternabond. I haven't had the time to fully investigate the problems but the top white layer has "jumped off" in several places and there was never full adhesion (and many wrinkles) on many edges across the roof where it contacted the virgin roof.
And I still have a leak somwhere! Is must not be on the roof.
