I've sanding a few Cozy/Long-EZ airplanes and I never had any problem with
rash or dust from that but sanding those UNI landing-gear struts will make
me itch for a day. Somehow those UNI fibers get pulled off longer and form
little needles.

Just a heavy long-sleeved shirt and a regular dust mask will do OK for me.

Hey all,
I'm planning on starting to build a molded kit in the summer and in
the meantime I'm trying to perfect my fibreglassing skills by building
a toolbox (and making all the rookie mistakes on it instead of a wing).
I went to the EAA sportair workshop which was awesome but it primarily
focused on the core shaping, laminating and bonding and not really on
sanding, trimming and finishing. Anyway, I need a tad of advice on
sanding and trimming excess fibreglass. First, what is the best type of
clothing to protect your skin from rashes and irritation from all the
dust? Also what kind of sandpaper should I use? grit? wet? dry? moist
:-)? Any other special considerations I should be aware of?

Thanks,
Omri
