RE: best microballoon mixture for medium repair
Likewise.
I don't understand why the Composite-ARF directions call for Micro-Balloons for all of the heavy load bearing construction of their planes.
I see a lot of my club members following the directions exactly, and I've always speculated that they are taking a risk by doing this.
Anyone have a suggestion for a better "filler" to mix in low quantity with Epoxy?
