Has anyone gone to the trouble of creating a pattern for using gripster material in the knee area.  http://techspec-usa.com/gensheet.html
Or does someone have a backing sheet off the 3M paint protection film?

If so, can I get a copy?

I find that My cordura pants don't grip the bare paint very well.

I used three of the templates, laid one on top of the other, and traced the largest dimentions.  I wish I had only done two of them; three makes it too large.  The ones I suggest are the Suzuki and the Honda.
