Good "putty" tape.
Solid, great for small repairs. I keep a roll in my rig, for " In Case" moments. Good tape, easy to work with. Buy a kids size pair of scissors, and put them in the box it comes in. Super convenient that way.

It does the job just fine
Quality butyl putty tape is just perfect for use when installing old school windows on my vintage camper. Adhesion is fine and it's easy to apply.

Butyl tape is easy to apply, easy to remove and very forgiving
I stripped down and rebuilt my 1972 truck camper removing all the siding down to the studs as well as all the fixtures like vents, windows and jack mounts. I used 14 rolls of this tape to seal it all back up. Things learned... 1. For the love of god don't use silicone to seal anything on your camper. When it fails nothing else will stick to it and it's pretty much impossible to completely remove with anything short of a wire wheel. 2. There is a sweet spot when it comes to the operating temperature of butyl tape. If it's too warm it will stick to everything including your fingers. If its warm and you roll out a long length it will easily stick to itself before you can apply it to anything. If it's too cold it won't stick and it's difficult to work because it's so stiff. If you apply it on a cold day and then tighen down whatever it is your trying to seal, later on when it warms it will squish out again and you will have to trim off the excess again. I often put my rolls of tape in the fridge for a bit on hot days and on heater vent in the winter. 3. I find that it's easiest to apply the tape to the object you wish to bond and not the surface you wish to mount it on. You should also dry fit the item you wish to seal first so you can identify any spots that may require extra layers od tape. Especially on corrugated aluminum. In that case I will apply tape generously to the voids on the mounted surface side. 4. Speaking of that, don't be afraid to use more than one layer of butyl tape. this tape is thin and you want ensure that all of the tape engages both surfaces and that you get a fair amount of squish that you then come back and trim off. 5. Like I said, the tape is far thinner than what they used at the camper factory. Figure for double what you think you will need. It takes lots and lots of tape if your camper is corrugated aluminum but not so much if it's flat sided fiberglass. 6. When it comes to trimming, give it some time to do its thing. At least over night. Then pick a nice cool day or early morning to trim off the excess. Its easy to make nice clean cuts as nice as when it came out of the factory whne the tape is nice and cool. In a perfect world you would let your freshly applied Butyle tape get nice and warm at least once and then trim it off when it gets cool again. You want it to squish out as much as possible before trimming.

does a great job sealing the little outside cracks / leaks on trailer - update
I have been using this stuff to shore up the seams, seals, areas around light fixtures on the outside of my RV. In my opinion, it's perfect, I can shape it like putty in the size and shape I want with my fingers and it goes along and creates a really nice seal. for whatever reason by accident i had silicone spray recently on my hand and that actually helped me a lot in not getting this stuck to my fingers while I was custom molding it to some select areas around the RV. my roof was in generally good shape but this was great for some shady areas that just needed shoring up. For one area on the back window, I applied it to a corner exterior of the window seam in a place where I suspected water was leeching and that problem has been solved, water no longer comes through the back window. That was over two years ago. The picture here is what that looks like about two years later. I cannot comment on how great it is technically. Someone with a degree in materials science can explain why this is apparently a good product for exterior RV uses but as far as I am concerned, it molds on great. I got the gray kind but so what it's a little gray .... I am much more concerned about the quality of the seal and could care less about color. It is also not all that noticeable. I can say now that after a couple years it just kind of looks like grey silly putty but has not been washed away or otherwise compromised. Disclaimer. I am a total amateur at this RV thing and have only nominal or no idea what I am doing but this stuff seems really great, like if you were all off a sudden got some roof leak, this stuff seems like it could be the total bomb. if you think it is sticky to work with, try spraying your hands with a little silicone and it will allow you to mold this stuff without getting it stuck to your hands UPDATE: over a year and a half after doing the repairs with this stuff, the repairs are holding nicely although this picks up a little dirt so some discoloration but that's quite minor compared to a leak

Great quality butyl tape for the price
I purchased this butyl tape to install Windows in my trailer. The butyl tape works exactly as butyl tape is supposed to. There's enough of a quantity of it that it was able to install two windows and have left over. There have been no leak since the installation. Would purchase again.

Excellent flexible, waterproof sealant tape. Make sure the surface is clean and dry, good for a number sealant applications. Reasonable price and easy to use

The double-seal tape with two-sided adhesive is an excellent choice for vacuum bagging in composite fabrication. Its strong adhesive properties ensure a secure and airtight seal, which is crucial for maintaining vacuum pressure throughout the process. The tape's build quality is impressive, with a durable construction that withstands the stresses of vacuum bagging without losing adhesion or integrity. It’s easy to apply and conforms well to various surfaces, making it highly reliable for composite work. Overall, it’s a must-have tool for anyone involved in vacuum bagging composites, offering both performance and durability.

Dicor products are some of the best RV sealing products out in the market. I installed new roof vents, stack pipe vents and fans using this product. Easy to use and has never failed me.

一般的なブチルテープは黒色な印象ありますが、こちらは粘土みたいな材質で色も灰色です。 粘土みたいに少し伸びます。 これが良いのか悪いのかは、劣化具合を見てみないと分かりませんので保留。
