Features
- Heavy-duty Material : Made of polyethylene with 3 layers( a layer of permanent sealing adhesives, a layer of tough braided material and a layer of waterproof plastic film), which is long-lasting, tear resistant and supporting long-lasting use.
- Great Adhesion: Permanent adhesive patch to cover up or protect the underneath of your RV. When placed over holes and tears, the repair tape bonds tightly to the bottom closure material PERMANENTLY. Eliminate taping the rips and tears in your underbelly repeatedly.
- Easy to Use: Cut a strip of tape slightly longer than the opening, then stick the tape and press the edge of the tape firmly so that the tape can be tightly bonded to the underbelly material. It would stick stronger if using a blow dryer or heat gun, apply heat to the tape. Do not overheat.
- Universal Use: This tenacious tape can repair damages underneath RV caused by debris on the road or a tire blowout and repair mobile home underbelly damage caused by animals and people making repairs; It was used to block off areas to prevent air, debris, or from entering.
- Clean Before Using: Thoroughly clean surface and ensure that the area around the torn part is clean and dry before applying the repair tape, otherwise the belly tape would be easy to peel off.

This is a very nice tape. It’s sticks extremely well, so proper placement is critical. The tape needs a peel away backing which would allow for ease of placement. I used it on my large slide out where I was getting slide marks (rub) on each end. Did a really nice job ! It’s has a slick feel which was a good thing for my purpose. Would buy again !

This worked VERY well to seal some slits in the underbelly of our camper. I would definitely buy this product again and recommend it. Mice got into the camper through openings where they ran plumbing and didn't bother to properly seal. I cut some slits in that underbelly protective layer to vacuum out seeds, stained insulation, etc. Once everything was successfully cleaned up and restored, I washed it all down with alcohol and used this tape to seal the slits that I had made. The tape was super sticky, even a little hard to get off the roll, but it stuck extremely well to the camper's protective layer. Knowing what the dealer would have charged to do the same work that I did myself, this tape was an excellent value for the money. It also looked just like the protective material that came under the camper, so it didn't look at all out of place. I've been about 2000 miles with it on the camper so far, through rain, gravel and dirt roads, and it continues to stick perfectly in place. I would say that it has great durability for having survived as well as it has so far.

This is excellent and grips the underbelly material. It will not break loose. I have helped family and friends after their underbelly was cut for repairs or the prior tape had come loose. THE KEY IS CLEANING THE UNDERBELLY CORRECTLY. Wipe down the area to be cleaned with a damp cloth to remove dirt and water marks; do it twice and wipe down with dry cloth. Let it dry. Put on heavy rubber gloves to wipe the area with acetone where the tape will be used. It will dry quickly. Move the cloth and acetone away from area. Apply the tape and use a plastic putty knife and pressure to smooth the tape. Finally step is to use a hair dryer and the putty knife to further press the tape on to the repair. Do the edges with special care.

Had to close up an opening in the underbelly after a tank valve repair. I bought the 6" wide, a bit wide for this use, I now would buy the 3" or 4". This stuff has very aggressive adhesive to stick well. But, better adhesion is made through preparation. 1. Wash down the surface with warm soapy water, then rinse we'll with a wet rag. 2. Wipe down the area with isopropyl alcohol, let dry for 5 minutes. 3. Apply the tape. 5. Warm the tape with a hair dryer or heat gun, press the tape down while warm. This is the best tape I have used for this purpose, all the others fall off after a few days/weeks. This has held up with no peeling.

I had a blow out on both sides of my single axle RV and it ripped the underlayment down and shredded it. This stuff is very easy to work with. I trimmed the hot mess away and cleaned the fabric to be repaired. I wasn't sure this stuff would hold. The repair went shockingly smoothly and I've had the camper going down the road at 70 mph a couple of times and I've had zero issues with the repair.

This tape seemed extraordinary when I first used it on our RV but only lasted a season before it began to de-laminate and peel off. It's still an okay product but now I know that it will require periodic replacement, which I can live with.
