You probably know this but if you are doing much spray painting, you
need something that will filter the VOCs. An N95 mask will not do
that.

VOCs can do nasty things to your central nervous system and brain.

The key to that respirator is the filter you attach. 3M makes a one time
use VOC filter that will even let you spray Imron. Use once, dispose.
As to nasty, friend bought his Mooney airplane because of VC,s, guy tried
to save money and painted his plane himself without a mask. I think Imron.
I used the one shot mask when I painted my Dune buggy about 35 years ago.

Yup, those are the filters I used when I was painting my boat. 2 coats
of Zinc Chromate and 2 coats of a poly based paint similar to
Imron/Awl grip. It lasted about 20 years. I scuffed it up a little and
shot 2 more coats of poly paint on it about 14 years ago.

I have a real rubber mask with filters for what I am shooting if it is
something really nasty like Awl Grip, Imron or whatever but if I am
just using a rattle can, outside, I go with an N-95.
If I actually shot a lot of that poly based paint I would get a
positive pressure mask that would run off my hookah.
These days I worry as much about particulates as anything. I am not
painting as much.

BTW that reminds me, Do you have a fiberglass guy who would gel coat
my spa? I might end up doing it myself but I would pay a guy if I had
someone I could trust. I can prep it but I have never shot gel coat
and I have heard your first swing at that ball might not work out so
good ;-)

Plan B would be to shoot 2 part epoxy of some kind. I suppose I could
brush it but it might be hard with all of the curves. Any kind of
roller is out of the question. I have air

Unfortunateky not, but you can get surprisingly good results brushing
or rolling gelcoat (several coats), and then rubbing it out - working
up through the grits to 1500 or so, followed by a good buffing with
rubbing compound. As you are probably aware there are two kinds of
gel coat, one without a wax additive for layering up multiple coats,
and the other type that has the wax additive for the top coat. The
purpose of the wax is to seal out the air which prevents it from
curing all the way. It's kind of fun actually, and of course you want
to practice on some plywood first. The nice thing anout gelcoat is
that it's very easy to repair if you mess up.

I have a friend who painted his older 38' Hatteras Sportsfish as a
DIY project using the "brush and tip" technique. Came out very nice.
Smooth and shiny.

I did a 28 foot sailboat that way a long time ago using 2 part
polyurethane . It came out well but was a lot of work and delayed my
spring launch time. That's the only boat that I've ever sold for more
than I paid however.
