I did not. I just cleaned the surface area and let it dry then applied 4” EternaBond tape on there and rubbed away to make sure I had a good adhesion. Been on my roof for 5 years with no peeling or anything.
I might have taken some denatured alcohol and done a quick wipe also. But not 100% since it was 5 years ago.
Does the Eternabond seam tape leave black streaks (runs) onto the fiberglass coach siding/rear/front clip?
Yep! Used it about 6 months ago and it seems to be working just fine!
The caulking that was used in the past was an ugly mess... Not that anyone would be up there but me! So I used the Liquid Flex Seal on ALL of my areas that needed to be protected and it not only Looks Great, but is doing the job! It was simple to use and cured quickly! No peeling up on the edges, cracking or anything! Super-Duper!
