multiple epoxy coat questions

[eskimo]

I don't think it needs a light sand as much as it just needs to be scuffed. Most important is making sure the plug is wiped down with either denatured alcohol or mineral spirits before the second coat.

I'm bad with time so I just give everything more then enough.

I've never used etex, but with system three, I wait for full cure, lightly sand with 320 and wipe with denatured alcohol. I know you can recoat without sanding or wiping down if still in the "soft set tack free stage". I always like sanding for a better finish though.
