My mini has a leak from the windscreen rubber.

I have bought a replacement rubber and while I was at it, because my screen has a chip and is de-laminating around the edges, I also bought a new tinted screen as it cost so little.

Question is, when I fit the new rubber are there any recommendations for sealing between the rubber and bodywork? If so what with?

Second question, I have been told you put in the screen by using string/cord around the rubber from the inside while applying pressure from the outside. Is there a recommended type of string to use as I imagine it needs to be pretty strong.

Any other things I may need to know?

There is windscreen sealant available

I don't use string around the rubber personally.  My old boss told me that technique, I tried it a few times but I much prefer my technique now.

 

I fit the rubber to the aperture, then I fit the screen into that.  I'd say most people do it that way really.  I assume you have the fillet tool for fitting the insert into the new rubber once the screen is fitted?

 

In terms of sealing, the rubber seal 'should' be enough.  Sometimes leaks by a little corrosion around the windscreen aperture, but windscreen sealants like above are not a bad thing anyway.  Whilst your old screen and rubber is removed, check the condition of the lip that you're fitting the rubber to.

Matt if you fit the rubber first then fit the screen into that, what do you use to manipulate the rubber around the screen?

 

The windscreen sealant, is this for between the glass and rubber, or the rubber and metal body?

Some people use a rubber fish slice/spatula. Basically something flat that can be used to prize the rubber around the screen. I've never done this, but have seen it done.

I literally used my fingers the last time I fitted a screen in mine.  It was a hot day and it went in remarkably well with the rubber being that tiny bit more flexible.

 

I fitted the last one I did in around 20 minutes, was very impressed with how easily it fitted.

Always best to do it on a hot day!!

 

I did this not so long ago, twice! rubber in first then the glass, far easier! i used plenty of lube and screen sealant(on both sides, to be safe), but yes youdont have to use it.

 

I borrowed a tool off a guy, non sharp point plastic thing and it works a treat did it in under 10 mins!

 

one of the easier jobs on a mini

[Marco1972]

As others have said do it on a hot day much easier put the rubber in the frame then fit the glass followed by the sealing trim
A little liquid soap always helps

I've done this several times now, and yes rubber seal in first then the screen, I start by inserting the glass into the seal at one of the bottom corners then start running the seal around.  Unless it's relatively new I'd recommend you get a new fillet strip (chromed plastic insert), these go brittle awfully quick and take on their own shape, re-using the same one is close to impossible.  For working the glass in these 'Pedro's) wide, slim lipped tyre levers are just superb:

I have bought a new fillet strip (chrome) with the rubber so thats covered 

 

Nice idea with the cycle tyre levers, I do have a pair of those in my garage somewhere!

 

Well I plan to do this job tomorrow so it should be a hot day which is a bonus.

 

Thanks everyone for the advice.

From the FAQ section of the board:  http://www.theminifo...ment-resealing/

 

Rubber to body, plastic spatulas for working the glass into the rubber, and use the proper lock strip tool, not a screwdriver.

Since the FAQ was written I have found a very good lubricant is/are the "personal lubricants" you can buy in the family planning section of your pharmacy.

 

As for the sealant, with a new rubber gasket you may not need it.  If in doubt or if the rubber seems puckered when the glass is installed, look for "Flowable RTV silicone rubber".  This is NOT the same RTV you will find for sealing engine gaskets.  It is a very thin RTV that wicks into tiny crevices.  It is clear and remains "gooey" over the years which makes it much easier to remove and clean up than regular RTV or the bitumen type black sealant that was used years ago.  Never use the modern windshield sealants used on modern cars where the sealant is also a glue used to hold the glass in place.  With the flowable RTV, it is easy to install using an applicator tip inserted between the body and seal or glass and seal before the lock strip is inserted.  Once the lock strip is inserted, simply wipe off any excess sealant that is squeezed out of the gaps.

 

In the U.S. I buy this flowable RTV from Permatex (a division of Loctite... who is in turn a division of Henkel).  They may now offer the product in the U.K.  If not, there is bound to be something similar.   The link below is to an eBay auction for the material.  I'm not saying that's a good price or vendor but it shows the product.

Advice that I received when I was rebuilding Lulu was, yes you can use soap, but in no circumstances should you use washing up liquid. It has a very high concentration of salt & will lead to unnecessary corrosion.

I love my mini - but not that much!

you can always buy a tool a mini place may even let you borrow/loan you one I find it makes it much easier and it makes firing the silver beading an ease
