Hi Larry, You are thinking of kevlar. It is the yellow colored fabric that is used for bullet proof vests and whatever humans can think of. The dynel I bought and looked at 30 years ago is a light tan color. I like fiberglass cloth better though. Larry H.
+++++++++++++++++++++++++++++++++++++++++++++++++++++ KR cloth is only $6.50 a yard at Wick's and it is plenty strong for the KR as proven by the many flying aircraft. Is dynel the cloth that takes a special scissor to cut and leaves little hairs when sanded? Larry Flesner _______________________________________
