Eternabond tape + Henry's 887 tropi-cool

[TenOC]

In my prior posting I discussed my plans to recoat my 5th wheel roof. Thanks for all your comments.

I have decided to use Henry's 887 tropi-cool. My plan now is to also use Henry's 885 to cover the seams combined with Eternabond tape.

My question is should I put down the tape 1st and then cover it with the 885 which I will then cover with 887 or put down the 885 and covered this with the with the tape which I then will cover with the 887. In other words should the tape be in the middle or directly on the roof covered by Henry's coating.

I’m a “tape first, then coat” guy.

I would tape first then coat.
That way the coating also seals the edges of the tape.

I always apply the E/bond before coating the roof. I don't know if it really matters, I just think it makes more sense.
