You want something more fragile than nitro ? Enamel on aluminium. Does anyone have a tip for a really strong clear over enamel in order to keep it clean ? Since I diy my pedal I like them to be hand painted (my gf do the job, and I'm very clumsy) I had this huge part that went off on a swirl. And this enclosure too I had better success with acrylic in durability but it's harder to get good color with it. Is there a way to get a really hard finish with a clear on enamel ? I'm using Johnson Klir (it might be a différent thing for the same name in this us) over it, which is a tip from scale model. Any advice ?
