What can I use as a topcoat that won't mess up paint or stain?

As the title asks, I'm looking for a topcoat to protect my work that won't smear the paint or dye used. Yes, I've waited for it to completely dry before applying with the same results. Thanks in advance.

I'm partial to spraying on surfaces that might smear. Either spray cans of saddle laquer, or an airbrush with water-based sealers. I use cheap $10 airbrushes, so if it gets gummed up eventually, I just replace it.

Thanks Michael. I'll definitely look to get an airbrush set up in the near future. I'll pick up some aerosol saddle lacquer to hold me over until I do.
