Hi,
I had 5 leaking corners grouped all together in a total segment of about 20 feet. Old thick grainy caulking was very tough to remove. Very hard and sticky. Best strategy to remove it was using a multi-tool (vibrating) with a small cutting blade. This was working greath but left a layer of residue. I used a glue remover called "The glue buster". It worked great and quickly. Then I used a wireless drill with a metal wire brush and wd-40 to disolve the leftover adhésive and reach bare métal (alluminum). I then applied a rich soapy solution and did the brush thing with drill using a new brush. I rinced everything to neutralize the glue cleener and the soapy residual. Then I applided an industrial grade cleaner to clean the whole gutter. A few days later, when weather forcast was good, I applied the seam tape. I used Windex on a towel to get rid of any greasy material on the locations to repair. Then, I used the seam tape. It was easier to apply than expected. I did not take any chance and I probably put more than required. With my pack of 2 x 15 feet = 30 feet, I only managed to do 3 corners instead of 5. I will have to order an extra pack. I put a single layer of the liquide rubber right now on 3 corners. I guess that quart that I am using Will be enough to complete the 5 corners with 2, maybe 3 layers. Put plastic gloves to apply then liquid rubber since it is not easy to remove it from fingers.
Repairing à corner is tricky and required more work than a straight section. Honestly, for all the work I had to do to prepare the 5 sections, maybe I should have paid someone to replace the problematic section but that would have cost a lot more and my time is free. I wish I would have find the multitool and glue buster and the drill wire brush before. The end result has a professional look and feel. Time will tell if it is a durable fix but I did everything by the book to get the best results. I will keep you poster.

Nice product, i put it today and the tape with the roof liquid rubber worked well

Liquid Rubber Seam Tape

I bought the seam tape and liquid rubber together. I'm replacing a bottom panel on my tank. It is time consuming to layer the liquid rubber, but will be worth it for the proper seal.

Product was very good. Was exactly the application we needed.
