No solo es un excelente sellador yo lo uso para fijar cualquier cosa, se pega y despega cuantas veces queramos, no mancha, no embarra, es una maravilla de material, es como un hule que pegamos y despegamos es Butilo!!

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。

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.

very sticky but works great thanks
