On vacation last week but when I got home my proseal finally arrived. I had everything prepped last night in anticipation of my father in law visiting today. The perfect helper to get me through the rudder trailing edge.
I ordered the 3oz proseal from Vans but was surprised to see they shipped the 6oz tube for the caulking gun. I was tempted to wait until I had more to seal, but thought trying to do the elevators and rudder in one session would be too much and I'm also eager to have some completed parts. Proceeding with rudder. I was only charged for the 3oz tube anyways.
In preparation for the proseal I realized that I had primed the wedge and the skin in the area to receive proseal. Some quick consultation of the forums seemed to say not to prime those surfaces. I did a quick scuff with 220 grit to remove a reasonable amount of primer and give the skin some bite.
Got the proseal all mixed up and confirmed the tube does fit in a normal caulk gun, at least it fit in mine. Applied a very thin coat to the trailing edge wedge and got it set in place. Had father in law hold back the top skin and set clecos per the plans as I did the blind rivets in the skeleton. All went really very easy. Didn't get too much extra proseal on anything and honestly I didn't find the smell to be a problem. It's all cleco'd up now and sitting for a few days. Proseal seems the way to go for me. Very happy with straightness of trailing edge so far. I used a long piece of aluminum angle from the tail cone to take out any irregularities in my workbench.
The other job for the proseal was going around the top of the VOR antenna conduit in the VS. Tough to get around the front side, but I think it is good enough to hold it in place.
Thanks Pappa Joe!
