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.

1st Attempt
Ok, however my application required more stiffness without any measurable smear.

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 : )

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.

Get 2228 instead for Bike Chainstay Protection
I should have read the other reviews first, 2229 is tacky on both sides while 2228 is more like thick electrical tape. 2229 is thicker than 2228 and can be trickier to apply for bike chainstays depending on the frame as it's not as pliable as the 2228. Learn from my mistake, if you're looking for a bike chainstay protection, go with 2228. This stuff (2229) is great, super strong adhesive, super thick, a lot of protection/seal but just be aware it is very tacky on both sides

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.
