I have used KG guncoat in OD green and in black, it is an awesome product, it does have a lower viscosity than ceracote or other brands of enamel based products, it also contains a teflon product that adds lubricity. Much like the fabled T-Coat that Walter Birdsong(R.I.P) utilized on the FBI HRT guns. I use aluminum oxide to bead blast my metal parts (barrel, reciever, front sight assembly, revolver cylinder etc.) The parts are cleaned and degreased. I put them in an oven and bring them up to tempature at 150 degrees (sorry about the oven honey). The parts are pulled out of the oven and sprayed utilizing an airbrush. I have had excellent results with the way the parts turn out, no orange peel or runs. My customers report to me that the product is both scratch and wear resistant. I have also used it on heat resistant plastic parts like grips with excellent results.
