Ummm, none is probably preferable.

Water always gets past sealant and gets trapped and rots it out.

Something like POR 15 is good if you already are covering up rust,
otherwise a clear drainage path over paint is the best in my mind.

I used to build trailers for Budd in the 70's. We used plastic tape between
the aluminum sides and the steel crossmembers. I wouldn't necessarily use
plastic tape, but you really need to have some barrier between the two
dissimilar metals. Galvanic action will start and in a few years your
aluminum will start falling off where it is corroding. My 2centavos FWIW.
Personally, I'd recommend against aluminum and just fix the corners
instead....

i was being a little sarcastic before, but if i were putting on corner
panels i probably would indeed tig them to the body. of course, this isnt
an option if youre using aluminum or stainless plate.

3m makes a sealant called 5200 it is a permanent attachment fer sure so if u
use it will be there for a while--most any marine shop should have.
