I want to put sealant on my boat what a good sealant to go all dawn bottom thanks for advice
 
Do you want to seal the entire hull ? or patch leaking rivets and welds?
Lots of choices to seal the entire hull. check out topic https://forum.tinboats.net/viewtopic.php?f=3&t=11977

For leaks, you will have about 100% feedback on the 3M-5200.
The regular 5200 is a little on the runny side, does not hold its shape like silicone.
but will flow into cracks and crevices with gravity (somewhat)

there are TWO types of 5200.
Regular - takes SEVEN days to fully cure. (yeah, one week)
Fast Cure - takes 24 hours to fully cure.
It is also an excellent waterproof adhesive.

I could not find the fast cure and grabbed a tube of the regular and sorry I did not
take the time to go to another store ..... the regular 5200 slow cure is messy to work with.

comes in the toothpaste tube size and also a caulking tube if you have a lot to seal up.
A little bit goes a long way.

Be prepared to pony up about 10-$15 for a 3oz tube.

Seams and rivets only. I think if you do entire thing it won't last as long, it will crack faster if you do the entire hull. Just my opinion from working with it. Gluvit is good stuff though!
