    I did a lot of research before I bought GTape. I did a lot of YouTube watching and I found GTape, it was being used by Dr Decks on YouTube. This guy's whole business seems to be nothing but decks so it seemed to me that if that's your whole business and your in a business that is generally based on referrals that has to be good. Getting up there in age and being the sort of person that doesn't like to do things twice I thought I use it. This stuff is fantastic in its ability to adhere to the wood. Living in Nova Scotia we don't get those dry desert days. I put it down on the beams and joist and I have to tell you make sure your lined up because this stuff sticks to the wood. It was almost a week before I got to the deck boards and it was still where it was supposed to be (stuck to the wood). If it does the job of sealing around the Camo Screws as it is supposed to do I'll never do the frame of the deck again. I gave it 5 stars because of it's adhesion abilities.

    Saw this on YouTube, Dr Decks promotes it and I have to say after using it I'm impressed. I did a fair amount of YouTubing and reading before I made my choice. I'm not a person that takes pleasure in doing things TWICE! Living in Nova Scotia we don't have the luxury of desert dry lumber where adhesion is guaranteed but after putting it on the Wolmanized lumber I can tell you if you rub it down and then try to lift it off it will take wood fibers off the boards. The real test came after a few days of rain when I could get back to the actual deck boards. The GTape was still where it was supposed to be. This seems to be an issue (Adhesion) with a lot of other tapes. Now if it seals around the Camo screws and keeps everything sealed as advertised I won't be rebuilding my deck in another 50 years. So I gave it a 5 star rating.
