I'd second using Butyl Tape in any application above the waterline that does not require the mechanical adhesive strength of one of the other sealant-adhesives. 4200 and 5200 are adhesives that work as sealants IMHO, not really sealants in and of themselves. Removing anything bedded in either is a PITA and can result in some serious damage to your boat.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Thanks again

Once again, I am glad I asked. After searching the threads for more information I thought I had it covered but came up with some more information with a new thread. I am glad i waited as well as I almost ordered a bunch of smaller tubes of 4200 and life-seal yesterday.

I will see if I can find some butyl tape at a local RV supply place. There are a lot more RV outlets nearby than chandleries in Utah. I will look for some 3m 101 as a secondary option. Any suggestions of where to look for either of these locally. I do have one drainage port I installed below the waterline in the boat that i sealed with silicone just to close it up, for now. Should I go ahead and use 4200 there? There is also a padeye mounted into the bow to attach to the winch for pulling up onto the trailer. It appears to be unsealed and even loose, I suspect the padeye part may be a Home Depot part. When I put a SS padeye there, would this be a good place for 4200 as well?

Also to clarify my plan based on all I have read here on the deck hardware rebedding:
-Pull off all hardware in one location. (I will brake it down to one area at a time, forward of the mas then aft)
-Clean up old sealant.
-Drill out oversized but not to exceed the size of hardware covering it.
tape underside of hole and fill with epoxy to coat and seep in then drain and fill with thickened epoxy
-Use hardware to drill out new holes. Bevel interior of holes.
-Use butyl tape for new bedding
-Mount using SS bolts and SS backing plate inside boat.

Thanks

5200 is NOT a bedding compound. silicone does not work for more than one season and is inappropriate for bedding---read the tube LOL.....i use lifecaulk---liquid for certain things on my formosa and regular for the rest----is an appropriate compound, as is 4200..silkaflex is also good..and some others-----but--if you want to have to redo everything every year, use silicone. if you wish failures, use 5200----that stuff doesnt come off easily either--is a permanent glue for mounting stuff not for bedding things-says so on the label, btw.........

Just to clarify, I have no intention of leaving the silicone on the plug. I only used it then as I had a hole in my boat below the waterline and it was the only product I had on hand to temporarily seal the hole, in case I wanted to go sailing before I could get it done right.

i have never tried silicone for that usage---i have used splash zone, but is difficult to remove for temp duties......

Not really that pad eye will be mechanically fastened and will NOT require a glue. If you feel like using a glue you can but you don't need to.

Should you choose to use 3m 4200 or the 5200 for whatever's appropriate, you can put the opened tube in the freezer as soon as you're done. I've found that it thaws out and is like new a few months later.

you might want to place penetrating epoxy into th escrew hole then bed the screws with 4200 then finish.....will never be a problem if you use the epoxy....seals the core and the glass.......just a hint for the wicked....from the wicked---it works well-----i picked this one up from a boatbuilder i knew long ago.......
