Default Looking for a sealant recommendation

Getting ready to replace misc items (rod holders, ctsy lights, etc.) none of which is below the waterline. I would like to buy 1 or 2 large tubes or a few small tubes of sealant but I was hoping to stick to one type rather than several. Should I go with 5200 or boatlife or something else?

3M 4000UV or Boatlife Lifeseal. 5200 is overkill.

Should I go with 5200 ...

If you screw it, use a sealant. If you glue it, use an adhesive. But, never, EVER, use 5200 on anything you might want to remove at a later time ...

4200 is UV stable I believe. Stays white.

Default sealant

dpowell x2

4200 is durable but removable for above waterline applications.

4200 not uv stable, if the rod holders are only screwed in and you are REALLY going to be using them use the 4200, otherwise boatlife silicone

Default Sealant Selection

Raybo is correct that 3M promotes 4000 as UV resistant product but I did not notice any application(s) in rjwilliams list that are exposed to UV. BoatLife is a also very good product.
