OK, I'll bite. What's kitty hair?

At first I thought maybe it was slang, but the top mfg of autobody filler actually calls it that as well.
It's fiberglass strand reinforced resin to be used as body filler.

Here I used it (the brown stuff, green filler is bondo to smooth the small pits in the fiberglass) to repair a missing chunk in a fiberglass visor on the old truck. Filled the entire void that was broke out as well as a backing layer extending beyond the repair on the back side.
