As a favor I repaired a silicone neck seal for @Colliam7. Here is the how to:
Step One: Tear your silicone seal.
Step Two: Use MEK to clean both sides of seal around tear.
Step Three: Apply 3M AC79 Primer to inside of seal around tear, try to get it in the tear as well without making the tear larger.
Step Four: Let primer dry for 15 seconds.
Step Five: Apply 3M SF100 Adhesive.
Step Six: Apply the adhesive to the inside of the seal first. Doing your best to get it in the tear as well as around the outside.
Step Seven: Allow adhesive to dry 5 minutes.
Step Eight: Repeat step three to outside of seal.
Step Nine: Repeat step six to outside of seal.
Step Ten: Repeat step seven.
Step Eleven: Verify both sides have dryed thoroughly.
Step Twelve: Set seal in safe place, allow to set overnight. (This step is not necessary, at this point the seal is ready to dive, I just do it for extra assurance.)
Step Thirteen: Reinstall seal in suit.
Step Fourteen: Go Diving
It might not look great to the naked eye, but it will keep the water out. I have yet to dive any repaired Silicone seal. So I am going to send this back to its owner and he will be our test pilot. (I am positive it will not leak) I hope to have a report back on its validity once it is received and the owner dives on it.
