You know when you paint your sitting room and you break out the masking tape to stick around all the bits you want to prevent getting covered in that weird green colour that's going on your walls?
Well, I'm certain you know the wonderful curvaceous ins and outs of a Gibson Les Paul.
Imagine having to fiddle about, awkwardly trying to mask off all that beautiful, curvy, binding on the top before you spray it? How much effort and time must that take in the Gibson finishing department every day?
Well, none really. Gibson don't bother masking the binding here before spraying that sunburst or that Black Beauty. It's just too much work. It's far easier to spray over the binding and then scrape it off again.
This Les Paul is being refinished with a black top. I spray solid colour (after some surface prep and sealing coats) over the whole top, let it dry a little (not too much, though) and then scrape the new finish off along the binding. It's actually pretty easy to use a blade, with a knuckle as a depth-stop, to remove the finish cleanly.
With that done, I'll let some of the solvents evaporate a day or two before starting on the clear lacquer top-coats (including a little 'antiquing' for the binding). This bundle of top-coats then needs to cure before being sanded and buffed out to a gloss—a gloss that I'll actually knock back with some gentle relicing to get things in keeping with the rest of the guitar.
None more black. None more beautiful.
By the way, you'll notice that the sides are masked. It's a lot easier to mask here than on the top and, often (as in this case), you'll want to keep the top colours off the side.
