Re: 1/8" milled fibers vs 1/4" chopped fibers for mixing w/PB
Don't you have any scraps of glass left over after cutting the fiberglass roll to fit where ever you're putting it?
Cut that up...... 1/4"+/- :facepalm:
Milled is much finer, the 1/4" make it more structural, stronger.......IE: Hairy PB <<---not what you get when the dog helps make the PB&J's sammies for lunch.
Different fillers for different applications.
