Sticky and rubbery - can't fault it
Not much to say beyond this does exactly what you'd expect. It adheres well to most surfaces and bonds really well to itself. I've used it extensively with no issues at all. Great product.

I have cleaned up 480 volt errors. Not typical but it worked.
Its best used to splice contractor errors. .

Good, flexible sealer
Used it to attach plexiglass to the sunroof hole on my car. Worked pretty well to seal it. Secured the plexiglass with scews.

This is good quality.
Must have for electricity work. Wear protective gear and know what your doing. If you don't know what your doing hire someone who does. Electricity will kill you fast.

Great for sealing electrical connections.
This stuff works great for sealing electrical wires or connections against moisture. In a pinch, I used these to cover areas where shrink wrap did no extend far enough. It applies like clay-doh and it is extremely tacky onto itself. Almost like bubble gum. The places where you can use this are only limited by your imagination : )

The best type splice waterproofing
The best type splice waterproofing. This is basically the same product as the old Raychem insulation mastic and mastic heatshrink products, no longer available in retail form. Is a gooey mastic that you mold onto connections to waterproof them - excellent for auto, trailer and boat electrical connections. Note because you are hand-molding it in place, it is NOT rated as insulation - you need to wrap with rate electrical tape to make a "safe" cnnection.

Quick tip
Easy to apply and since it was cold in january i had to warm it up a little to get the maximum effect of the adhesive. To clean up excess or smeared material i just uae soap and water right away and if you leave it longer itll really stick in there and from thay point u have to go with a little bit aggressive method which i use diluted acetone.

very tacky/sticky; stays put and does not move
Simple - I used this for a few bikes to quiet chain slap. I'm sure there are other uses as this stuff is versatile.

Expsnsive, but you get a lot
This stuff is amazing. It's exactly what I needed to use a chain guard on my bike. It's also great for other repairs. However, I was apprehensive as it was so expensive. Well, the box and roll shown in the product image is not the one you get, this is a bagged (no box) 30ft roll and 1.5" wide. The product shot/box shows a 10ft roll at 1" wide. I would have preferred to just get 10ft but it wasn't available at the time. That being said, the price difference is only $5 at the time of writing, which means this is a far better value. They do sell

For mtb chainstays
I didn't use it for it's intended use, I used it to protect the chainstays on my mountain bike. Works like a charm.
