Review: This is definitely the tape to fix camper underbelly tears or to do work and reseal - 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.
Review: Great product, make sure to clean for good adherence. - So far so good! Cleaned the underbelly of our 5th wheel camper and applied underbelly tape. Seems to make a great bond. Time will tell. Will give an update later on. Material seems thick and sticky. Should hold up great!

### ⭐⭐⭐⭐⭐ How to get this stuff to work like a champ!
*by C***C on April 13, 2024*

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.
