PC Products PC-7 Epoxy Adhesive Paste, Two-Part Heavy Duty, 2oz in Two Jars, Charcoal Gray 27776...

Stuff is amazing, strong, very sticky. Can be a little difficult to work with, but worth the effort.

It takes some time to dry, but it is worth the wait. It stands up to heat and wear and tear very well, and it is very shapeable and paintable. Literally the best leather fire helmet repair product on the market today.

This glue is excellent for the recommended materials. It will adhere steel pieces for example. After a set up period (when it wont stick to my fingers) I have formed it. I have carved and used a grinder on it after drying and using a protective mask. Its very sticky when parts are mixed like any epoxy.

This epoxy was not what I expected, but it worked well. Both components were very stiff (Like cold modeling clay) when they arrived. It took a lot of working (kneading) them to get them mixed. Once mixed I needed to aggressively smear the epoxy onto the counter base to make a good bond (It would not wet the surface of the cultured stone easily). Once in place the epoxy did not run or move in any way (which is a good thing if your counter is already in place). After 24 hours the epoxy had set although there was still some give to it. After setting for a week it is rock hard and solid.

It works great, The reason I could not give it higher marks is because you must know what the heck your doing. The epoxy and the resin hardener are not easy to mix and equal portions is most important. It is not a liquid or a gel or even a paste it is a very stiff substance, like C4. But please note that this is where it's strength comes from, and it is not 'easy' to be spread, you should have the right tools and know exactly what you are going to do with it. Cleanup will require something strong if you make a mistake (xylene). The important thing is you can fabricate anything , I have even used it the weld two pieces of hardened plastics. This will outlast any 3D printed piece , and I have used it even on my siding that had a couple of bullet holes. I applied the material in a measured amount, using a flexible putty knife. Then I removed any excess with the aforementioned solvent. A day later in 40 degree weather it hard enough to apply a small hand sander to feather out. Then I painted over it- and viola- bullet holes are gone and can now sell my house without question. Fixed broken lamps, works great with metal and glass and hard synthetic surfaces. Not the best for softwoods- lastly- as long as you don't mix it it will last forever- I still have some that was from 35 years ago, and I tried it wondering how it would do. The catalyst did take about twice as long to work but in two days it was as hard as a rock- It's aquarium safe- but wait a few days for complete cure and then was product of with soap and rinse well
