Howdy All! I use to work in a pharmacy that sold lots of makeup. Stocking shelves I came across some pretty awesome colors in the nail polish section. I always said I would give it a try someday and well here I am . . . So here we have an Ambrosia Maple top on Douglas fir back. Here I am applying BIN primer. I did so with a brush then sanded flat. So the back color is a Duplicolor product: I have to say, difficult to get this stuff to spray without spitting and general difficulty after doing the first pass. I had 3 cans (probably could have done it in 1) each had the same problem. After the first spray, even if it was cleaned after the initial use, it would spit, continue spraying after I took my finger off the button. It was a hassle. I dig the color though. This was after the first layer, I was digging the fact that the grain had enough sink to it that the paint visibly showed the grain. However after the 3rd go round the grain was filled and is pretty much flat now. I tried to do the standard burst type thing with the duplicolor,that was just a complete fail. The thicker finish material looked crappy on the edges and the burst had too much of a hard line to it not enough fade. This is a process I've done with rattlecans of Behlen's at least a dozen times and gotten excellent results but not with the Duplicolor. I eventually sand this back. That's when I thought about the nail polish idea I've been kicking around since I started building. So I took this. Mix 3 parts color to 1 part lacquer thinner (the expensive kind like the SW or Behlens stuff) into an air brush. Although not as green as the bottle it sprayed on very nice and it shifts colors depending on what angle you are looking at it from. It looks super blue here in the photo and in the shop lights but more green in natural or sun light. I am super pleased with the look and I will definitely be using this again. It did not have an issue over the duplicolor and my test piece with string instrument lacquer over the top looks clear. I can't wait to get to the clear coats on this guitar. So what do you think?
