RE: use for micro ballons


Microballoons should never be used for structural purposes (glue, joints,  etc.). I don't think that they'd be appropriate for Shearwater fillets. They are excellent for making a lightweight, easy-to-sand filler and fairing compound for painted parts. Because of their purple color, most people wouldn't use them on bright-finished parts (except maybe Camper).

Hm...hadn't thought of that particular finish.  Do they make them in day-glo orange?

I used them in my end pour on my Wood Duck. Just trying for something to be able to drill through for a handle/toggle.
