How do I maintain Single Stage Acrylic enamel?

Single stage with hardener......old school, boy does that bring back the memories.

It will be awhile before the paint is fully cured (you can smell the solvents for many weeks, usually) so no waxing. Keep it clean as possible , but wash with cold water and mild soap when needed.

The last car that I painted acrylic enamel was 20 years ago with a Binks #7. It's a good system I think, your's looks real nice too.
