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.
