Without getting into a weld-on war, it appears that one of the difficulties is that the weld-on tends to run/drip on vertical surfaces like the rear windows or door windows (if installed with door attached to cabin top).

Would it help to put the sealant on the window itself rather than the cabin top? This way the acrylic window could be laid flat, sealant put on in taped off area of window with minimal dripping, and then placed into the cabin top joggles. Still would be runoff/drip at this point but might work better??

Thoughts??

Thanks in advance,
Tom Hanaway

Hey Tom,

I like weld-on and had no problem with it. It is really tough stuff. I made a small spatula out of scrap door trimming, spread a layer of weld-on on BOTH surfaces (plexi and fiberglass) -- spread, it doesn't run -- and immediately (it starts to skin really quickly) mated them. I only used enough pressure to get any bubbles out -- it is a contact adhesive, not a pressure one. I used straps with styrofoam, no clamps, and got no cracks or hazing whatsoever. You can't dawdle, at least in the summer heat, or it will set up in your container before you can apply it. Spread, it doesn't set as quickly, same as any epoxy.

Then after it was well cured, I ground about an inch wide shallow overlapping 1/2 inch each on the fiberglass and plexi around the whole perimiter. Just deep enough to lay in a layer of glass cloth to cover/fill/bond the joint so that there will be no cracking of the paint as it later heats and cools in the sun.

I did this on doors, windows, and windshield. I have pictures I've previously posted of this, and as soon as it warms up to 60 here, I should have painted pictures also.

Later, - Lew

Tape the inside surface of the window C apply weldon to both the cabin top flange and the window C place window in place on the cabin top C apply cleceos and then pull the tape. Remove all weld on strings from the inside of the window with rag and what ever solvent you are comfortable with C me C (DA). Any stuff not removed become permanent C fast. 

You will be left with an ugly glue joint on the inside of the plane...either buy those fiberglass window gap seals or be handy with a caulking gun and proseal or other colored sealer. I used proseal as my cabin top interior is painted with charcoal zolatone. 
BTW- one needs about two weeks for the stink of the proseal to go away before working on the inside of the aircraft.

Tom

That is the way did all of the windows and it worked very well.
Sorry no pictures (there was no time).
Rehearse for each window time is very critical.
So is temperature, I wouldn't try it above 70 deg.
Check Tim Olson's site for additional details.
