I don't remember what I had gotten it for, I did use on some spiral
wound tubes for reinforcement, but was told the same for it's use in
comps.
3# cut is 29% solids, if dried out would look like this,

Wiki says it's a thermoplastic.
I say it's bug poop.
Been used for a lot of weird stuff.
As Lloyd says it has a shelf life.
When it's powdered, is it exempt from shelf life?
I got a can last year, thinking of using it like Marlowe.

Use around 4 times the amount and let the alcohol eva****ate, like

I was told you could, but "why?"
I'd rather watch paint dry than wait for mail.
Have found Shellac and other goodies at Bent spoon, and will get some
