I'd think there will still be oil based for steel/iron and for wood
decking, however most people are now using fiberglass decking/fencing,
color is built in so needs no paint. I don't think many use oil based
for indoor house paint. For concrete most would choose an epoxy
paint. I used to build plastic models and painted those with a paint
similar to nail polish, least it smelled like nail polish. But that
was very long ago, there must be different paints now.

When we first moved here and went to paint the living room, the
largest room, water based paint litterally slid off to the bottom from
gravity. We discovered that they used an oil based paint (ballpark
mustard yallow) that they had left over from their factory down the
road, their family owns a local company that builds custom high end
metal furniture and other expensive metal products, like automoblie
elevators... Hollywood people like Jay Leno would order them for
storing their many vehicles.
That ballpark mustard yallow color was awful, so in the end we sanded
the walls in that entire 20' X 30' room... we used those rubberized
electric vibrating palm sanders. A dusty job so we suited up and wore
respirators... it worked, we were able to use water based paint with
no problems. The ceilings throughout this house are 1' sq. Celotex
tiles... excellent sound absorbtion and adds great insulation. Easy
to paint with a roller.
