## Questions & Answers

**Q: Does this product have a smell?  Does it off gas?**
A: I used it outside, and did not notice any smell.

**Q: good for sealing taillight lens  on my camper ?**
A: If you're sealing between the lens and the body, yeah, it would work.  This is kind of like a tar compound...it is flexible and sticky so kind of think along the lines of pushing some chewing gum in a crack.  It's not going to be pretty when the bulb burns out and you have to remove the lens to change it, there's going to be some residue left.  but it will seal up the crack for sure.

**Q: Is this for RV skylight?**
A: It should work great for an RV skylight. I use it to seal windows on boats so you should be fine.

**Q: If I apply this in sub-50F degree weather, does adhesion improve when temps go up? I'm using it under a solar panel mounting bracket, with screws.**
A: Do you mean below 50F or did you mean minus 50 F? It took me a minute to figure it out. I assume you mean below 50 but not minus 50. Anyway yes to your question if it's below 50 but if it's minus 50 I'm not sure how it would hold up to apply. As in frozen state it might be brittle and getting the film off it might also be difficult. Anyway our temps here in NW MT have surprised us and warmed up above 50 in May nicely and that includes evenings. Often if you are in a warm climate you need to put in the fridge for a day or even freezer for a few hours to help you manage the properties of the butyl caulking. Think of this as a line of caulking in tape form because that's basically what it is. Also some people use two layers and over lap ends when they come together well beyond just a smidge think more like an inch or more overlap. It can spread out a bit. Good luck with your projects and some people like to apply in cooler temps because it can be easier to handle. But way below freezing probably NOT.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good quality butyl tape that stays where you put it and seals well.
*by L***K on July 8, 2025*

This butyl tape is as good as any I've seen. It's a reasonable thickness, deploys easily and stretches/compresses well during installation. I used it for a shed window installation that was followed by a drenching rain. No leaks and I don't expect any for the life of this installation.

### ⭐⭐⭐⭐⭐ LLPT - Quality Butyl Tape
*by A***D on October 8, 2022*

I've used good butyl tape in the past for sealing above the waterline deck penetrations in boats. And I've refused to use bad butyl tapes...as they are just not worth the effort to use and often make a big mess. I needed some butyl tape to install a replacement RV roof vent fan and my usual go-to stuff was unavailable, so I decided to give this one a try. I can say this appears to be quality stuff.The roll came shipped in a cardboard box so it wasn't a crushed mess like some others you can order. The initial feel was virtually identical to the stuff I usually use. It is a bit sticky/tacky, but not overly so and pliable, but not overly soft. I squeezed a small piece between my finger and thumb for a minute, then pulled them apart and it did stick and stretched quite nicely...indicating it should provide a good seal at normal temperatures.I ran a couple tests with two small pieces to check how it dealt with temperature changes. One piece was mashed between a folded piece of cling wrap and placed in the freezer (-2F) and another was placed between a folded piece of parchment paper and placed in my toaster oven on warm (160~180F). After 20 minutes in the toaster, I removed the parchment paper and peeled the paper apart. The butyl was just a bit softer than room temperature but it didn't flow/melt and still had good structure. It adhered to the parchment paper and stretched like it should. I (accidentally) left the piece in the freezer for over a day. When I took that one out and tried peeling the cling wrap apart, the butyl again stayed stuck to the film and stretched quite well. This is exactly how a good butyl tape should be...remain pliable and a bit sticky for the whole expected temperature range.The only thing I can't judge right now is if this will remain flexible over time, but it seems like it should. If it does, it will make a very nice and permanent seal. I had no hesitation about using it for my RV fan install project. I will update this review if I find an issue down the road, but I do not expect one at this point.For those that have never used butyl tape, here are a couple hints. Butyl tape is not an adhesive, it is a sealant and requires another means of structural attachment (usually screws). For a good, water-tight seal, apply the tape to the object, then tighten the mechanical fastener (screws) until snug and the butyl is squeezed just a bit. Then let it sit a bit so the butyl flows (ok, not flow but slowly squeezes) and stabilizes. Then go back and tighten a bit more. Repeat this process until the items is secured. You can then use a plastic putty knife to trim away the excess. You can also use a ball of the sealant pressed/tapped against the oozed out sealant to clean up the seams. Just don't pull at it. If you keep the ball of removed sealant clean, you can even reuse it for another project. I recommend warmer temperatures if possible, as it makes this process go more quickly. If done properly, butyl will make a very good, long lasting flexible seal.So, my initial impression is this is a good quality butyl tape and is highly recommended.

### ⭐⭐⭐⭐⭐ Excellent Seal – No More Leaks!
*by M***E on June 23, 2025*

I used this LLPT Butyl Tape on my RV roof and around a few windows, and I’m seriously impressed. It’s super sticky, easy to apply, and creates a tight, waterproof seal just like advertised. The 3/4 inch width was perfect for detailed work without being messy, and the roll was plenty long for multiple jobs.What I really liked is how flexible it stayed—even in colder weather—and once it’s down, it doesn’t budge. Great for sealing vents, skylights, trim, or anything that needs to stay leak-free. Highly recommend for DIYers or pros who need reliable sealing tape that actually works!
