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.
