These gaskets are a freaking nightmare guys.
I suspect if I did it everyday of my life it would be a no brainer. I've blown too way too much money on test plexi and the gaskets. No longer worth it to me for speed, look, quality.
Alternatively their is a nice alternative that I will be investigating and has good reviews/results.
In regards to rope method/cars/trucks;
The gaskets where they use the rope for the automotive windows are factory, 1 pc and fit perfectly to the old cars or new. They actually if you look at the vids the gaskets from mfg make 90 deg. rads. So they must be a complete different rubber. The rope method will not work here. In fact the rope does not stay in the opening.
The rads with even heated water/tape don't actually conform and want to exaggerate. primarily the mfg made gasket is a neat application but being custom its not. In addition a rubber has to be installed to tighten the glass up. This will not happen if you try to put the gasket on while on a table then try to install the window with a rope app.
Moving along.
Their are other vids on the same subject posted below. My opinion. Guys who are trained in this biz are fine to use I'm sure. I'm pretty mechanically trained and again do not recommend this approach. I could go to a local window guy but that defeats the $$ purpose.
POOP says I! I could have knocked out alot of other things. Always a learning curve it is says I! Arrgg.
