Review: I actually use this to seal up busted drysuit seams. It's thick, but pliable, and takes forever to set, but in that time it seeps into the neoprene pores and fills anything from problematic pinholes to blowouts. stuffs tough and flexible, just a pain to use because of the cure time. worth it though
Review: Tarda en curar pero cuando lo hace queda bien aderido

## Questions & Answers

**Q: 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**
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.  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.

**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. Allow five days to cure. Don’t use the fast cure.

**Q: Is it paintable?**
A: Yes it is paintable

Delivered on time, well packaged. Used on the boat transom to fill in transducer screw holes. It's easy to use. It does take a week to fully cure but works perfectly. I recommend for anyone working on a boat. Use a caulk tube plug to seal and save unused product.
