Thanks for the replies. I have the install tool that came with the seals. I will try the lube but it seems like it will still be impossible.
I'll let you know how it turns out.
I'd imagine the tool they supply is not of the best quality,the ones I use daily the loop section the strip passes through is made of spring steel.
This is similar to what I use except I have individual fixed ones for different size lock strips.
Here's a
link to a little 'how to' I did a while back,just in case you're overlooking something,the technique is the same with corner glass.
I hope it helps.
Don't use too much 'lube' as it'll get too slick and fight you all the way.
I just use plain old spray glass cleaner,or a spray bottle with water and mild dish soap solution.
NO silicon!
Good luck.
