[PSUBS-MAILIST] glueing aluminum

[Douglas Suhr via Personal_Submersibles]

Hank, on a new box trailer that I just purchased last year, the
aluminum skin of the box's exterior is glued (epoxied) at the seams as
opposed to riveted. The option costs a little more, but looks better
than the riveted skin, IMO.

Another advantage in the case of the trailer skin is that it doesn't
require silicon sealing with epoxy welds as it would with rivets, so
again, it looks better. There's a small 3M sticker on the trailer, if
you want, I can take a look at it tomorrow. I remember when the guy
was trying to sell me the option, he showed me two small I-beams glued
together with the stuff and they seemed pretty strong to me (though
I'm not a hydraulic ram either, so...).

Glad to see you're on FB! ~ Doug S.
