Peter says:
I wouldn't even recommend it for spreaders, unless you're looking to
replace them every few years because of the ultra violet degradation.
But how about an application as an RF firelighter?

What would you recommend for spreaders, not on ladder line but for
parallel dipole spreaders? Delrin is readily available in both natural
and black. The black has good UV resistance.
