Help with do I seal up or allow to drain?

Hello,  Man has tried for centuries to control mother nature.  Ultimately it ends in failure. 

I haven't seen the pics but here's how I try to ward off electrical failures.  First, I solder all connections.  This will eliminate most problems.  Then seal connections by smearing with silicone sealer.  While still "wet" slide shrink wrap over the siliconed connection.   Don't do like I do and forget the shrink wrap until after I solder the connection 😤  Make sure shrink wrap generously overlaps the connection. Now heat the shrink wrap.  This makes a fairly permanent connection.

As for the box.  I would put in drain holes.  I would also make it easy to open for cleaning/drying and maintenance.

Here's a weird thought.  Could you put a breather like on a differential in the bottom??  Would that help keep out water yet let any that got in drain??

So I know more then a few of you have seen the photos of my rear electrical junction box in CHUG's Project thread. I am at a decision point. Do I try to seal up the box (really not possible) or do I drill some nice holes in the bottom (what looks like the top in the photos) and make sure any moisture that does get into the box can find an easy way out. OF COURSE doing that makes sure that water from any kind of water crossing deeper then the top of the Rear cross member will cause water to enter the box.

Either way I am sure if I go into water it will get into the box.

SO whats your vote?
