If I use rustoleum to paint my OLL receicer and aluminum handguard, will it stay on or will it peel and flake off?

Mostly depends on your prep work and coating thickness.

Preparation preparation preparation.

You will need to get some sort of handheld (or automotive sized ) spraygun and some reducer for the paint. I would bead blast the surface.
