As I am just finishing up removing the old gaffers tape from my polypro hoop with paint thinner (it's all I had), I have an idea.  "Armor All" helps protect our automobile interior vinyl from UV rays.  Can it also be used to protect polypro hoops?  I am aware that it will leave it kinda slippery until it wears off, but does anyone know if it could be bad for it in the long run?
