If you need one of the best epoxy adhesives this is it.
This stuff works great for carbon fiber bonding. My only experience was assembling a 2.5mm carbonfiber sheet and carbonfiber rods. Be diligent about the prep work and the pieces will move after you clamp them. It has a good working time which is helpful if things don't go according to plan (like always). If proper prep work was done it is incredibly strong! The part I assembled, when it was cured, was able to withstand 200lbs(me) without a creek or crack.

The quantity in the description is wrong
I kind of figured the price was too good to be true. They say 12 per case in the description, but this is actually quantity one not 12. 👎

1 tube, not 12
Glue itself is good, description is deceiving. Only ordering 1 tube not 12

An epoxy adhesive you can trust
As always DP420 is amazing. I use it for Carbon Fiber/Titanium/Aluminum/ABS/Home repairs. It’s an epoxy adhesive I’ve grown to trust over the years.

You’ll need to buy a dispensing gun and tips, too
I guess I’m naive but while the glue is excellent, as a first time user the description should say you need a gun and tips to dispense the glue. So after spending another $20 I was able to use the glue.

Great stuff but NOT 12/case
Worked very well but expected 12 tubes - got 1 and not sure worth it for price / tube at 1 ... just beware
C**B
This is only one tube
Beware it is not 12 but rather just one that you receive
