I'm about to finish my second fabric finish guitar and would like to keep doing more, possibly to sell. But so far I haven't been completely satisfied with the durability of the results. I don't have a good place to spray so I'm limited to wiping or brushing on finishes. So far what I've used is gluing down the fabric with Mod Podge, applying a few coats of shellac on top of the fabric, and then layering on Minwax polyurethane. And Minwax has been a mixed bag - one project will dry hard as a rock, other times it never quite passes the fingernail test, leaving a slight scratch behind if you scuff it. I'm ok getting a *pretty good* result on my own guitars but would like something I can trust more if I'm going to sell my work. Also, if I can find something waterborne that I like, I much prefer that to dealing with containers of mineral spirits getting all gunked up with poly goo. So I begin my test pieces with the following lineup: General Finishes top coat Bona Mega floor finish Target Coatings urethane Crystalac And Minwax just to give it another shot I'm just a few days in, so I'll have to give everything proper cure times. My main criteria are, can this be rubbed out to a nice looking finish - gloss or satin - and does it pass the fingernail test? Past that I'm pretty flexible. If anyone has more suggestions I'm open, though I have to resist opening my wallet too many more times for now. Thanks.
