I needed to fix a water leak at my back glass and couldn't figure out how I was going to do it. I did not want to remove the back glass if I didn't have to because it is to much work. I ended up thinning out some RTV with mineral spirits so that it was more runny. Put it in the back of a syringe and injected it between the glass and the rubber where it was leaking. The RTV dries just like it would normally but takes just a little longer. Would be nice to use a larger needle but a .80mm needle is all I had. I had to squeeze really hard even though I thinned it. They make much larger needles. Just thought I would pass it on because it worked great!

 

Normally those type of leaks are not an issue of lack of seal but a lack of structure behind the seal. Those types of repairs generally don't last long.

 

This is my restored car, It didn't have any rust in the frames. I just read the Steel Rubber gasket directions and it said to not use any sealer when installing. Well, it leaked around each of the trim clips. I used this on the inside with the trim off where I could get to the clips easier. I was meaning in general, I could see other uses for this than the glass.

 

Great tip, thanks..

 

 

Now those are cool! I may pick up a set of these!

 

I searched “mono jet syringe.” Had the inspiration from when I was a ute. We’d steal syringes from science classroom, take a ball inflator needle, grind the tip to the needed configuration and then epoxy them on to the syringes.
