Dicor CS200B-1 Seal-Tite Corner Seal Tape - 2" x 50' Roll - RV, Trailer, Motorhome Repair Tape

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.

We really liked this product. It was very easy to apply and the adhesion was excellent. We have a 15 year old trailer and we decided it would be good to seal the corner seams on both front edges. We just noticed a small leak on a front corner on the floor and we believe the leak began in a front roof top corner and ran down the front edge. We resealed the front roof edges with lap sealant but also decided to do the front vertical corner edges too. When we removed the vinyl trim we noticed the four top screws on the metal corner trim on the side with the leak had rust on them. We removed the corner trim pieces, applied the Dicor corner tape, cleaned off the old caulking, added new butyl tape and reattached everything. We have had one rain since then and could not find any evidence of leaking so it seemed the corner tape and new sealant worked well. Thank you, Dicor for an excellent product at a good price. And we have enough tape to do the back two corner edges as well. We watched a YouTube video for additional instructions on how to do it.

This was far superior to the original sealing material on my 2009 travel trailer. Be sure to clear the surface of old material. This is about the stickiest tape I ever used, so be sure you have it where you want it before removing the glue covering.

Works great for sealing camper corners. Affordable and easy to use.

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.

I remodeled a 28 year old Lance truck camper. I removed all the windows, roof vents and rebuilt and replaced all. I would recommend using this Dicore when ever you are doing a RV project like this. It adheres excellent and adds another (first) layer of sealing protection.

I love this stuff. I used it to reseal my 2004 Toy Hauler and most recently around some trim I put siding over.

This product waterproofed the seems of my rv. It has held up through multiple seasons.

Great product for your caravan

Super sticky and does a great job of sealing corners and seams. Instructions was a little lacking in that you have to peel the clear tape of the surface to apply. That fact was not clear in the instructions. Once exposed, the tape will stick like super glue so be careful to apply to exact place you want. Clean surface is important for a proper application.

Amazing product works as seen, easy installation and seals up really well!

Can't say to much as seems to seal well but only time will tell.

It’s as advertised, it went on easy seems fairly strong! People said it was impossible to remove and once it’s stuck on and rubbed down tight it is but while installed if I stick on one side and didn’t really stick hard I could pull up and move over a bit but once I was done and rubbed it down good to stick it, well it ain’t coming off.
