Can you use nail polish top coat on top of acrylic paint as a clear coat?

I did a custom paint job on my Tippmann 98 paintball gun which is made of metal. When I just did the lettering, I found that the acrylic 'tomato red' paint was pretty dull, so I was wondering if I could add nail polish top coat on it to make it shinier and preserve it? If not what should I use?





I want it to match the white gloss enamel that the body is sprayed with.

I think that would work and preserve the paint.
