This stuff works like a champ. It can repair the underbelly material of an RV like nobody's business. I have an RV and Toy Hauler and this is all I used to do the repairs I had to do on the underbelly. Basically the material for an RV underbelly cover is like a 4-6mil tarp material that is very strong and durable. Because it is not normally exposed to direct sunlight it can last a long time but sometimes they can ripped because of running over a very high rock, or a stick pokes up in there and tears it, or perhaps you had to do some mods or fixes to your RV and you had to get in under the floor and cut your way up from the outside. This stuff is almost the exact same material and it is sticky as hell. Here is how to make work like a champ:Pro-tip:1. First, prep the surface. This is really basic stuff and we all know that you should prep the surface and we all get lazy from time to time, but the complaints about it not sticking are obviously bad prep jobs or people who didn't prep at all. Clean off any dirt with a sponge or the like and let it dry. Then give it a quick shot of denatured alcohol to make the surface pristine. Let the alcohol dry for a minute or two and put this stuff on and it will stick like it was meant to and it will never come off.2. Tape from both the inside and the outside if you can. When I was doing floor repairs I had access to both sides and taped both sides and the tear is now stronger than the rest of the underbelly material because it's doubled up and because I prepped, it is never coming off.3. Get more than you think you'll need, it goes quick. I ran through more than I expected doing repairs and ran out. You must go well past the tear on each side to get the best strength so be sure to order enough.4. You can use a little heat to make the material soft to pull it together if the rip has been there a long time and is really wide open. Prep the surface, use a heat gun and soften up the material, pull it together and slap this stuff on and bang, high and tight again.5. Finally, if you have a big hole that is missing a bunch of material, put in a some backing screen or the like. Tape the screen over the big hole really well with the screen on the inside if you can. Then tape the outside and inside covering the screen entirely with a layer on both sides. This will keep the integrity of the material and you won't have any leaks and it won't come out if you do it right.Last tip: You can use this on tarps by using the same prepping procedure and the same times and it works absolutely flawless.

This stuff works great. Had damage under my RV after a double blowout. After the original tape was torn from the incident, I removed as much as possible right down to the metal. After putting in new foam insulation, I used this tape to re-establish a seal. My RV under the wheel well is totally water tight.

Very satisfied. Blends nicely with textured black under wrap. Works extremely well to seal cuts/splits in the vinyl underbelly of a mobile home, R/V, vapor barrier, and house wrap. It is VERY sticky, and somewhat of a challenge to unroll or reposition once applied. It works best if you first clean the application area with 70% (or stronger) isopropyl alcohol and remove all remaining residue with a clean cloth or paper towel. Keep the alcohol on hand to remove adhesive residue from the scissors or whatever tool used to cut the tape as you go. When working alone, don't cut a piece longer than 4' to prevent the adhesive side from coming in contact with itself.

This works great for adding insulation to the underside of our trailer. For curves and angles, a little warming from a heat gun softens the material so that it can be shaped. Once it cools, it holds the shape.The extra special, super expensive tape fell off the next day. Don't bother with it.

We bought this to repair the underbelly of our house after my husband had to do some work. Man is it good stuff!!! We also used a little bit of it to fix a sled that had cracked and so far its holding up well. Worth the buy.

Great adhesion and unbelievably tuff. Used it to repair several things, even a rip in a large tarp. Held up without an issue to wind blasts of 50 mph.

This stuff is amazing for fixing and patching under belly of rv. It is very sticky if you don’t get it in the rite spot the first time it’s stuck so be very patient and take your time. Highly recommend this stuff.

This was purchased for an RV awning. The tape was applied and immediately gave way. The awning was cleaned appropriately and prepared for the product. Useless. Did not work.UPDATE: The seller reached out to me about the product not working and issued a full refund. Although the product was not useful, the customer service from this seller is OUTSTANDING.

Used windex to clean surfaces to adhere to. Let dry completely. Cut tape to fit with lots of overlap. Work the tape to ensure it is well stuck including all edges. Does a nice job so far.
