Just wondering what people recommend as a sealant between the windscreen rubber and the car? Any particular ones to steer clear off? Also do you really need to put sealant between the rubber and the windscreen? I would assume it would do a good enough job on its own.

So what are your thoughts/opinions on this and what is the best way to go about sealing? Would you; after rubber is in, run a bead between the rubber and the car, or would you try and run a bead in the rubber before fitting and try not to get crap everywhere?

And no i don't need information on actually fitting the windscreen/lock strip

Cheers

Just done the Troopy windscreen and used Selleys D-Mastic and it filled up some big gaps OK.

Stood up to a tropical downpour this arvo with no leaks so happy to use it again.

Cheers

If it's a new rubber it should be fine.
I like to leave mine clean but there's no risk in adding a little sealant like scooper does above (particularly in the tropics!).

Gotta make sure you let the rear window sit in the new rubber a few days before cutting the rubber to fit. This cut is where the leaks will occur.

Stickaflex works well.

Don't be tempted to use any of your everday silicone based sealants because they can react with the metal and cause premature rusting around your screen seals.
You can buy tubes of proper windscreen sealant from places like supercheap for $10-$15. Last one I bought was Septone brand I think, was cheap and worked a treat.

Drying silicone releases acetic acid, thats why the fumes suck.

Back in the good old days people would use the silicone if it started to leak and yes the acid did cause them to rust and leak more.
I have just refitted my rear screen and used D Mastic. I put it in the groove for the screen as well but not much. Make sure you have some kero and then soapy water to clean up the job as it gets messy.

Proper windscreen sealant to use is butyl mastic. It doesn't cause rust, won't dry out completely until it's 20 years old.
Everybody sells it, even Supercrap.
<edit> I only use it if I get a leak, not usual with a brand new rubber.

I haven't used sealant on either front or rear screens on both road and race car for many years, do use new rubbers tho when installed and never had any leaks. Can get the proper 1 piece rear rubber from Windsreens O'Brien.

Mini King has the right size rear rubber too.
The ones Kc sells are UK Mk2 on, they need to be cut to fit Oz Minis.

Sikaflex if you have to use anything......but you shouldn't need too.

Guess I'll be giving John a call from now on in regards to these items.

We didn't use anything for Cherry's windscreen rubber and it doesn't leak

I would not recommend using Sikaflex (as in Urethane), unless your rubber is stuffed, because you will destroy the rubber if you ever need to remove the window in the future.

Toyota used Urethane on the rubber fitted late model 80 series crusier windscreens because of the passenger fitted air bags. Most passenger fitted airbags use the windscreen for deflection of the airbag. Most windscreen replacements on these will need a new rubber.

As has been said, new rubber, no sealer, if it leaks, use butyl mastic. Mini screens if they leak will normally leak screen to rubber, and not body to rubber.
