I am in the process of repairing a rotted deck core. The
area is about 6 sq ft and is built up with polyester cloth.
Is there an additive to thicken polyester resin to use as a
fairing compound? Can automotive Bondo be used? Will fairing
compounds as found at West Marine or Bondo stand up to
typical deck activity or will they crack?

Any info would be great!

John

There's some stuff to add to the resin that is basically very tiny glass
balls that looks like dust. Comes in a can on the same store-shelf as all of
the fiberglass resins, etc. I've used it to patch holes and the like. Works
great. I'm sure that someone out there knows the correct name for the stuff.
Thickening compound?

Cheers,
Steve

Dont use bondo. It expands when wet, and your fairing will become unfair.
Use micro or glass balloons.

Microballoons?

I will look into a tickening agent but I thought microballs
was an epoxy additive.Could the heat generated when
polyester kicks could melt the balls?

No more than the heat generated when epoxy kicks off. ;-)

I think they're just refered to as glass beads. RAKA sells some. Other
places too.
