Confirmed: sanding these parts 24 hours after spraying 2nd coat and the
paint
is not dry. Gummed up the sand paper.

Boy, does this Rustoleum paint dry slowly... It says 48 hours, but at
this
rate it looks like it will be longer.

Is Krylon a better choice? Or...?

Thanks.

Rustoleum is good paint. There are other heavy-duty enamels, from the
majors, but most straight alkyds are going to take a long time to dry
hard.
That's just enamel. Rustoleum probably is slower to dry than most. In many
applications, they don't use a second coat. It's better to use a good
primer, and then the top coat will lay on a lot thicker than each coat
used
without primer. Get a compatible primer made for use with the enamel.

There are a lot of industrial-type paint systems out there today,
including
several polyurethane systems that are tough and that produce a nice
finish.
Probably the toughest is two-part polyurethane, which comes in brushable
versions. Don't touch the spray-coat versions unless you study it well.
It's
highly toxic and you can't protect yourself with just a respirator.

Rustoleum takes at least a week to get as hard as it ever will, which
isn't very.

There are respirator cartridges that are NIOSH-rated for urethanes.
The more significant issue is getting a good face-to-respirator seal.

You go first. I'll watch. g
