window seals-

I have an 81 gillig 636.

As far as I can tell, it has lived it's whole life in Washington state. The windows are mostly in good shape, however, there is a bit of leakage going on... The most noticeable problem is at the two larger, non-opening windows toward the rear of the bus. This is where the gutters end, so water has been encouraged to pool and focus on gaining access to the inner frames causing rust problems.

I called and spoke with a very helpful woman at AZ bus sales today, but alas, no dice, at all...

So, any ideas for where I might be able to obtain something like this? Alternately, has anyone out there had any luck carefully peeling off the old seals, giving them a good cleaning, and putting them back with some kind of silicone or other sealers? Cause that's what I'm thinkin I might have to do!

Re: window seals-

Silicon may help/work for awhile but there are much better sealers available then silicon. It would very likely be worthwhile to stop into an RV supply store (Camping World or some such) and ask a couple of questions. Anything with the letters RV on it seams to cost more but you can probably walk out with a tube of sealer that you will be very happy with for $10.00 or $15.00.

Re: window seals-

check with an auto body/paint supply or glass shop for either rubber window gaskets and or sealer. a lotof the older/larger gaskets are extruded shapes available on a roll and you cut them to length. you could also check out the hotrod and custom car magazines for someone that specializes in window and weatherstriping, I know that they are out there,I just don't remember who they are.

Re: window seals-

I am thinking about resetting my windows before painting. Luckily for me, I spent 15 years installing auto glass, so it is a no-brainer.
What you need is a cross-section to compare and measure if need be. Have a look around here... ... tory=19748

I have an account there, pretty much if they dont have it, you probably dont need it.

Flat glass can be had from any half baked auto glass shop. It is the curved stuff that gets tricky. Same goes for replacement gaskets. You may not find an exact match for anything that old, but a decent shop will have access to literally hundreds of profiles, many of which will work fine.
