Has anyone used something other than pro seal on the trailing edge of
the rudder that doesn't require mixing and isn't so messy?

I used clear RTV on the trailing edge of my elevator, worked great, and wish I had known about it when I did my rudder.

I tried the T-88 epoxy. Did not like it any better than proseal. Called
Vans. The purpose of the adhesive is not structural, but to help hold the parts
in place. They said that there was no problem leaving out the proseal step.
I like that best. Fast, clean, straight edges. For note, I used the
pneumatic squeezer for the first very gentle set, the a couple of taps with the rivet
gun.

"used clear RTV on the trailing edge of my elevator"
I have heard, (you know that can be, though) that RTV may corrode aluminum. Probably the acetic acid as it cures. Something to watch. This was noted by some people that used it to cure the oil-canning of -4 and -6 type control surfaces. Also, keep it away from your canopy, unless it's the type approved for electronics. Once again, just stuff from past threads on this forum. FWIW etc.

I must admit I had heard some people say this also, however I decided to use it because several others had with no problem, the manufacturer says it is designed for aluminum, and I must admit I live in the driest climate around, a few miles from the military "Boneyard" where they store aircraft because nothing corrodes! I also used it very sparingly, just a few "drops" to hold the structure in place for riveting... Glenn in Tucson.

Jeff,VAFst a quick one. The builders manual calls for a dab at the T/E
internal bends of the tail feathers. I also put some clear RTV at the lap
joint on L/E of the rudder for vibration purposes but will remove it due to
overkill and someone telling me it was not necessary. Plus paint don't stick
to well to that stuff. Anyway, about the fly-in we are starting to gather
some cool little prizes for the event and I will post soon an RSVP notice so
we can better accommodate our guests. Bruce

The early 4 and 6 rudders ( .017 skins) had a problem with cracking at the leading edge of the stiffeners in the rudder. It wasn't in the directions to apply RTV to the stiffener and rudder spar gap, but I did in my second rudder. Yes, I like others replaced mine due to cracks starting from the forward most rivet on 6 stiffeners, and used pro-seal.

The acetic acid is added to RTV to etch metal for a better bond, and it's "corrosive" effect is short lived.

Permatex makes a non-corrosive RTV called Ultra-Blue----guaranteed
non-corrosive to metals. I used it and so far nothing's turned to powder
yet. By far the most damaging thing to my trailing edges was
over-zealous pounding from my 3X rivet gun!
