The white guys are subject to ultra-violet degredation . . .
they also don't take kindly to hyro-carbon and ozone exposure
both of which are found in fair quantity under the cowl.
Ty-wraps treated for better resistance to environmental
stresses are always colored . . . most of the ones I've seen
are either dark green or black. However, it's possible to make
a ty-wrap from funky plastic of ANY color. When you buy them
new in original manufacturer's packaging, it will state on the
lable whether or not the critter is resistant to UV and/or
chemical attack.
My personal preference under the cowl is MS21919DGxx clamps
and/or Dacron flat-lace (string) . . . I've seen both of these
products work well for decades under the cowl.
