Window sealant

Recommended Posts

In all my sussing prior to putting mine in ALL recommended either what Lateral said and/or what IT said. Not a single soul mentioned any other products, including the nice dude who cut my new windows, he was a Dow Corning fan.

 

I also use the VHB tape with the Quilosa MS35. I put the 3M primer on the windows where the VHB and MS was going. It's keyed very well. Be well prepared, the Quilosa does tack off reasonably quickly. That can be handy as you can get it on and 30mins later it's skinned up well enough to handle light rain and drizzle.....but not probing fingers :)

 

I have some VHB tape and primer if you need any. Enuff primer for about another 60+ boats, it goes a long way.

As above....

VHB tape. .. Test your tape first or use 3M. Dont use the thin stuff...you need flex.

and a low modulus scilicone.  

If you use scilicone then tape/mask a boarder onto your windows that lines up where the scilicone will be.

Gently rough up the area with 360 grit ...(Careful to keep it only where the paint will be) Paint that area with a scilicone based exhaust paint.

This painted area is called a frit. You will see that it is on all fixed windows on cars . Its purpose is to protect the tape and scilicone from uv degradation. 

Somewhere on the net is a several page article I wrote about 14 years ago on window installation with step by step pics....but I cant find it.   :roll: .  

My windows have never leaked or look like doing so in the future... they have done many thousands of miles

Yep use 795 and VHB. Avoid screw/fastenings if possible (Thermal expansion). Discussion may need a little more focus on how attached ie external,rebate,frame and if perspex or lexan.

Our perspex windows leaked from day one, no screws.  I have now added machine screws, hopefully that will fix it. If it doesnt, the windows may have to be replaced with fiberglass with a clear resin. Can you put a dark tint in a resin that will still allow light to come through?

Buthyl rubber sealant has work fine for me. Applied in 1986, still no leaks in 2019. I don't know what brand name but this looks right:

This stuff neither cures nor dries out. It is still soft and sticky.

Why bother doing that, glass it up and put a big window shaped sticker on the cabin side. Never leak.
