Does the 10oz. Silicone require purchasing a special caulk gun? I was previously shipped tubes made of metal with pull tap opening like on a soup can

I was concerned as well but it has an internal plastic follower cup that a traditional caulking gun presses against: Similar to the traditional caulk tube. The additional metal seal helps to prolong the storage of the adhesive sealant.

Has anyone tried mixing a color pigment into the glue before application? Will this effect the cure?

I have not and can only advise you give 3M support line a call and ask them and if you can I am sure they will tell you which coloring to use. I would not just mix in any color you don't know how the glue will react to it. Give 3M a call I am sure they will be glad to help.

My kitty put a couple of pin hole sized punctures in my scuba bcd, causing a small, slow leak. will this patch it?

Yes it will. Allow five days to cure. Don’t use the fast cure.
