It's highly recommended to follow the paint manufactures recommendation for
fairing. Depending on the density of the Microballons they may be too soft
to sustain long time use, causing cracks.

I need to fair large deck surfaces in prep for paint. The repair thus far
has been all polyester, can I use microballons to create a polyester
fairing compound?
