I have found that just about any of the colored marking tapes dont
hold up well outdoors.

I assume you mean tapes like surveyors use as well as temporary tapes
printed with "Police Line" or "Caution." *These are generally made of
polyethylene because it is so inexpensive. *Exposed to ultraviolet light,
polyethylene is destroyed quickly.

To add to something "Dave" said, Dacron is DuPont's name for their brand of
poly(ethylene terephthalate) polyester fibers. *Other fiber names are
Dacron, Diolen, Fortrel, Kodal, Tergal, Terylene, and Trevira. *I have seen
hamfest dealers charging considerably more for Dacron rope just because of
the name. *Likewise Mylar is DuPont's name for PET film, but PET films are
also known as Terphane, Hostaphan and Melinex by different manufacturers.
