How do you preserve this for future use. Mine dried up after about 6 months. I don't use it regularly. Is there a secret for preserving it?

Try putting some Dow Corning 111 silicone grease (https://www.amazon.com/gp/product/B00CTUJNU2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) around the cap after it's sealed. It will keep air and water out, will stay in place, and is easy to wipe off when you need to use the epoxy again. It's food grade so you can use your bare finger to spread it around the cap.

Will this adhere rubber gaskets to hard plastic that will be underwater?

Under the applications uses: marine; plastic& PVC; fiberglass, concrete, metal, wood, tile & ceramic,auto repairs, home repairs, industrial, outdoor equip., craft, trucks, marine, agricultural & equip. motorcycle, toys, and plumbing.

How is the clarity of this epoxy? Does it cloud after cured?

I used it to fix a refrigerator door shelf and it cured completely clear

It is this waterproof?

Once cured it is waterproof, but not intended to be applied in water. If you are looking for something specifically for water (e.g. boat, water tank, spa, etc.) you might consider this: http://www.jbweld.com/product/j-b-waterweld/
