Review on 🔧 PRO Tapes & Specialties Pro Flex Flexible Butyl All Weather Patch and Shield Repair Tape, 50' x 4", White - Ultimate Protection and Versatile Fixes with 1 Pack by Trevor Rodke

I bought this tape to seal the seams between the boards on the balcony. As mentioned, the tape is sticky so you need to be careful when installing it. That was me, and the tape stuck well. I have since painted over the tape and should note that a second coat is required in some places to fully cover the tape. We haven't had rain yet, so I don't know how well it will sew up; I'll get back to you after the next shower and report whether it went the way I wanted or not.
