Jeff and others have been asking about pool paint and latex (acrylic)
house paint.
Maybe I'm wrong, but I think the only way to spray that sort of paint is
with a big, high pressure airless rig. The other alternative, with those
paints, is to use a roller. I like to use a small cup gun to spray my
finishes.
For a small cup gun setup you need something closer to an automotive finish.
As I mentioned earlier, I have always used Pettit Poly Poxy paints.
I'm sure there are dozens of other good products. I have also used
DuPont automotive finish a few times, with good results.
I have many times painted the outside of a wood fiberglass boat,
while leaving the inside a clear, unstained natural finish (varnish over
faired epoxy-fiberglass). But, from a maintenance point of view, it
makes more sense to do the opposite. The inside of the boat is what takes
a beating, and what takes the most ultra violet exposure.
A Painted hull, natural finish seats and gunwale:
You can make a very handsome boat by painting the hull, inside and out,
while leaving the gunwale and seats a natural finish. Few people do this,
but it makes a very handsome boat, and paint provides much better long
term protection for the hull.
Final Tip:
When painting a hull inside and out, I like to choose a similar but lighter
color for the inside (same color but much darker for the outside).
You can do this by cutting the outside color with light gray or white paint.
Then, once you have double coated the inside, fill the pot one last time
with the outside color. Then twist the head on the cup gun to wide open,
so it sprays big drip-like splats, rather than a fine spray.
Take a deep
eath, hold the gun a little further back and spatter the
inside surface with evenly spaced but fat, dark splats. I like the look.
The colors always match (because one is a white function of the other)
and it really COVERS UP FLAWS.
I'm an old house framer, not a finish carpenter. In a lot of ways I'm the
opposite of Jason.....who is, among other things, a real artist. I guess what
I'm trying to say is that Jason does near perfect work, with a real eye for
graphic balance. Jason doesn't need to cover anything up.
But I always do!
And a two-tone spatter finish on the inside covers flaws like no other finish.
