Best tape
This tape does the trick. Works as advertised. I also bought the fix it tape and can tell the quality of this product outshine the cheap brands. I found this to be a little expensive but plan on sticking to this brand for future needs. The product was used to seal some electrical wires to an outside lamp. I had to go back and undo it and found that fusing was no joke. I easly cut it with a knife and peeled away like rubber skin. Word of warning when wrapping items, please make sure you streach it out as you are apllying and don't get ahead of your self by removing the protective plastic. If the tape happens to crinkle on to itself then you may get lucky and be able to straighten it out. When they say self fusing ... it will. At this price you don't want to waste.

Great stuff
Great stuff, be careful when applying because you won't get a second chance to fix your wraps, it is that self-adherent. You end up ripping it if you have to remove.
