Need some help with fairing, etc.

...Better to make your own fairing compound out of cabosil and micro balloons and then put a layer or two of glass over these areas that require a lot of putty.

Chuck,
I've never used cabosil, but I have used microbaloons. Does the cabosil make the cured putty brittle or hard to sand? I recently picked up another product I'm going to try, 3M Glass Bubbles. Here's the description from U.S. Composites web site:

"These hollow glass microspheres can be added to any epoxy and polyester resin. These bubbles will make a lightweight, easy sanding putty for minor surface filling of cracks, holes, etc. (Color: White)"

I like that it will make a white putty instead of dark brown like the microballons. I'll post results on my Resto thread after I've tried it out.
