clear coat

i don't think it would be a hard enough finish. for nails sure, but for a box that your stepping on etc.. i'd think it would get dented and scraped off too easily.

noname acrylic lacquer, good enough?

yeah, i think laquer is pretty tough, with spray laquer, you probably want to do a few thin coats letting each coat dry between rather than one thick coat. laquer is kind of syrupy and can trick you into thinking it won't run, but if you lay iton too thick it will.

i've used enamel on bare metal, its a bit brittle and so a few of my boxes have a few chips in the paint but it bonds to CLEAN aluminum pretty good and it dries very hard .but i think that envirotex epoxy stuff looks great and pretty easy to use.
