Take a look at Dow 795, boat builders use this to install windows. I did. Its a urethane structural skyscraper window glue. Cheap too.

Thanks guys from thread starter. I already ordered Vans replacement window, so that's that. I like the idea of over-sizing the holes for short section of tube, as well as countersink.

As to the sealant, I think it may be an important factor on the 12 especially, 'cause of the fuel filler location just above the Lexan margin. Careful fueling to avoid splash-over, and immediate clean up of any drip(s) may be as important. For that matter, sealing the right side with tank sealant would be considerably more important than the left side, as the filler is on the right.

If the sealant used doesn't resist petroleum well, I'd just as soon skip the sealant step all together. It's a messy, time-consuming job, which really complicates any future window replacement, too. Finding a co-worker to fit comfortably in the baggage area of the '12 was a challenge, too!

Thanks folks!

JRo

Byron,

What color is Dow 795? Is it impervious to gasoline? I'm looking for something light in color. Was thinking of coming up with a fuel filler vent to prevent "burping" during fueling, and just skipping this sealant step.

Scott,

Was the Vans supplied window intended to have a specific service life (e.g. 5 years)? My thought is if I can get comparable life out of cheaper material it would be worth my while to make my own replacement if I ever need one.

Default Cut and drilled raw edges are the problem.

The Lexan has a special coating and is protected. The cut outer edge and the drilled holes are the problem. Oversize the holes a bit and coat the inside surface of the holes and the cut outer edge with laminating epoxy using a small brush and maybe a pipe cleaner for the holes.

Has anyone tried Stika (sp?) instead of the drilling and rivets?

Default AluminumFoil Tape

Could you wrap the edge with 1/2-inch or 3/4-inch wide Aluminum Foil Tape?

I am at the point of sealing the rear window and also do not want the sealant to show through the window on the inside. Was considering painting the bottom half inch or so of the lexan the same color as the interior...which is self etching primer. Any reasons why this should not be tried?

I have fitted my rear window but have not permanently installed it yet. When I had it in for a test fit, I marked the outside of the window along the aluminum edge. When I removed the window, I trimmed away the protective coating, masked the edge, and painted the outside lower edge gloss black. I did this on my windshield on my Rocket and it turned out very nice. The sealant will be applied on top of the paint and thus, the inside will look the same all the way around.

Guys - read this thread- http://www.vansairforce.com/communit...ad.php?t=89721

The tests were never done though. Metal tape is discussed. Still have to seal the screw holes. If I was doing it over, the metal tape and a hypo squirt of silicone into each screw hole is what I would do.
