Silicone require purchasing a special caulk gun? I was previously shipped tubes made of metal with pull tap opening like on a soup can** A: 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. **Q: Has anyone tried mixing a color pigment into the glue before application? Will this effect the cure?** A: 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.

Give 3M a call I am sure they will be glad to help. **Q: My kitty put a couple of pin hole sized punctures in my scuba bcd, causing a small, slow leak. will this patch it?** A: Yes it will.
