Interested to know how long the original BUG4/Goat covering lasted, was it always stored inside and when on the truck rack did it have a cover over it?

The polyester fabric (Dacron) which I use to cover airchair structures is the same material as that used for boat sails, hang glider wings, and paragliders, so I follow the same practices as they do. My gliders, which use unprotected fabric covering, are always stored under cover to minimize solar exposure, which would cause cumulative weakening of the exposed, unprotected fabric over time. (Another result of radiation exposure is that it appears to cause unprotected Polybrush to turn brown, which looks bad on white fabric).

I've considered using conventional protective coatings of aluminized paint, which would allow me to tie my glider down outside for as long as I wanted to. All I have to do to protect my fabric against radiation is to complete more of the Polyfiber process by using the protective coat, Polyspray. It's just additional work, and a little additional weight (I wish somebody would do it and tell me how much weight is added, a pound or two, maybe?).

The flexible sails ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
