There's nothing wrong with acrylic lacquer per se; it shoots easily, is very forgiving, covers well and won't yellow. It skins over very quickly, but the cure time is dependant upon several variables: how may coats,
how much time between coats, temperature and humidity at time of spraying and while drying. The upside of acrylics is that you can lay on an insane amount of paint before you get runs, and its very hard to make it blush or "pinhole". The downside is the same as nitro; you have to have a huge amount of patience while the stuff cures to the point of practical hardness, and it will suffer the same durability and longevity shortcomings of nitro. I just shot the last coats of acrylic clear on a bass body tonight, I'm probably looking
at assembling the guitar late this summer or early this fall. Next time I refinish a guitar, I'm going over to
my buddy's body shop and shooting catalyzed poly. It's easier, faster, and is way more durable.
Good luck.
