Dicor CS114B-1 Seal-Tite Corner Seal Tape - 1.25" x 50 '

I used this to repair/reseal the aluminum corner beads on my fiberglass 2016 Gulf Stream Vista Cruiser. The tape is very, very, very sticky and therefore a challenge to work with, but man does it adhere to the fiberglass! Tips: Once you figure out how to peel away the clear plastic film, make sure to maintain at least an inch or so of plastic beyond the tape itself. Try your best to only touch the adhesive with one finger at a time, LOL. I discovered that you can sometimes use the plastic film to hold the tape as you apply it. It's surprisingly thin; thinner than the butyl tape I removed. Use a SHARP utility knife to cut it, starting on the fabric side so the knife doesn't get stuck. Try not to stretch it too much length-wise as you lay it down... easier said than done. I applied it first to the vertical wall surface, which is where I set my guideline (less than 1/4" from the edge of the fiberglass). After applying 2 feet or so, I'd lay the roll on the roof or just stick it to the side of the camper, then go back and fold the tape over the corner onto the roof. Try to stretch a bit as you do this to "pull" the surfaces together. Then I used the side of my utility knife to smooth the back of the tape and "set" it. Take your time and prepare for some frustration. (The prep will take you longer to remove the old butyl and silicone (use mineral spirits and a plastic scraper)). Have already driven through several hard rains and it's working. I've also used it in place of butyl tape under marker lights and when replacing the stove hood exhaust outlet.

Nice material very sticky .Installed on the corners of our trailer and put buytle tape over the top. Worked very nicely.

I bought this to seal the corners of my camper as it had extensive water damage from prior owners, not taking care of it. You need to clean the surface very well before applying, and make absolutely sure that where you lay this stuff is where you wanted to stay, because does not peel up! It will stick on and ruin the piece that you are using. If it’s not super hot outside, maybe go over it with a heat gun just to make sure it is sticking well because it sticks best in warm weather or in the sun.

Was skeptical at first but this stuff worked amazingly to seal up the corners on a RV I repaired. Would definitely recommend.

This stuff not sure about . Its paper thin.
