Bed assembly help-70 steel floor

[Low Elco]

I hope yall can help me. I have a 70 with a steel floor and new bedsides and tailgate. I have several questions.

1. Did you paint all the edges or just run with ecoat/primer? If yes did you just use enamel or the real stuff? We'll be doing Al's when we go to paint.

2. Did you assemble the panels into a bed of seam sealer?

3. Did you assemble to a set of measurements or just line up with the tailgate and headgate?

Don't know why this has me so tripped out, but it apparently does. Any help yall can give is much appreciated, thanks!
