I find myself looking at a paint collection that includes:

* Testor's MM Acrylic gloss coat
* Vallejo Acrylic gloss varnish
* Future floor wax

I've used all three and all three seem to airbrush out just fine. But I'm curious... for armor models, is there much difference between the three? I'm really just using it to seal the base finish before decals and washes and other weathering.

Is this just a personal preference issue, or is there real advantages to one vs. the others?

Thanks!
