Using Eternabond Tape to Seal Rain Gutters

With the Eternabond being 4" wide can I apply it over the rain gutters with the idea of smoothing it into the profile of the gutter and along the edges so there is no air space?  In other words, do I have to remove the gutters to apply the Eternabond?  I'm not being lazy, just don't want to make more work for myself than is necessary.

How much extra work can it be?  If you are going to go through the expense of eternabond, I would imagine that the BEST way of doing it would be to remove the gutters, apply the tape, seal the seams, and then coat the roof.

You will never be able to smooth Eternabond into the gutter profile.  It is so sticky it will end up with ripples that will block water from flowing properly in the gutter.  Once it is stuck, it is stuck, there is no pulling it back off without stretching it and making a mess of things. 

Pull the gutters, apply the Eternabond, then reinstall the gutters.  It'll look a lot nicer than trying to cover the gutter. 

I sent an email to you offering to sell you the remaining 35' of a 4"x50' roll.  I'm in Anchorage near Service High.

Also, If you're in Anchorage too, you can pick up as much elastometric roof coating as you need for free over at the Muni's Central Transfer Station.  The Household Hazardous Waste program has a freebie section where you can get paint and stuff they'd normally ship outside for disposal.  They had a bunch of that roof coating on Saturday.  They're open Tuesday, Thursday and Saturday.

I don't know off-hand if the 4" tape is thicker than the 2", but I used the 2" and did form the tape over the screws and it doesn't block the water channel and it seals over the screws as well.  I had to do it this way because of very limited time to get it done.

However, I agree that putting the tape under the rail is the best way to do and, if you put the gutter over the tape, you won't need to add sealant to each of the screws as you go either.  The tape will squish down from the pressure and seal the screws.
