Subject: Re: [rebel-builders] Sealing: EP420 vs ProSeal
Should the sealer (EP-420) be applied wet to the faying surfaces including
onto the rivets just before assembly? Or would it be best to paint the
surfaces and let it dry before riveting and not coat each rivet?
I have been researching corrosion on faying surfaces and have seen many
opinions from credible sources. In conclusion it makes sense to use
Polyfiber EP-420 on the faying surfaces. For example an engineer from
Boeing states that they prefer to assemble dry.

you might want to take it apart someday !! Almost impossible
to do without damage with ProSeal ... ( and it's heavier ... :-( )
The EP-430 seals the joint tightly, and can be thinner.. with no flex.
Just MHO ...

Don't use silicon anywhere... you'll never get it out of the pores to
make the paint stick to the aircraft. Every seam and overlap gets put
together, in anything I build/assemble, with WET Polyfiber EP420 just
before riveting.
You definitely need a bunch of small 3/32 drain holes though, in
strategic places, in the outer bottom of the fuselage !

Subject: [rebel-builders] Sealing the floor question
Happy Thanksgiving, everyone!
I am at the point of (small drum roll, please) installing the rear
floor, and it occurs to me that any water that may leak into the
cabin would run down the rear floor, hit a seam at the interior
corner wraps, and wick under the skin, and maybe collect in the bays
beneath the floor. Has anyone used any type of a sealant in the
joint between said corner wraps and the floor?
I have looked for a mild sealant, but the only thing that seems
desirable would be some of that strippable silicon sealant. I know
that regular silicon sealant is a pretty good glue, and I didn't
want to use that. Am I fixing a problem that doesn't exist?
Thanks
