Finishing a guitar! Obviously...

I am a couple months away (hopefully sooner :mrgreen: ) from being able to finish my guitar, but I am just trying to sort everything out before I get to it. I have decided to do this... grain fill with MinWax stain-able water-based wood filler (It says "guaranteed to accept a stain") then use leather dyes, like the ones stewmac carries, that are solluable in water to dye a sunburst. Then I have some clear lacquer from Watco. I just want to know what people have to say about brushing on lacquer, and how to get it a mirror finish. I want this guitar to shine like a brand new corvette. :grin: So I would fill, sand, dye (and all the steps accompanied), then brush it on, and sand once, only after the very last coat? I have the option of using a spray gun, but it is a cheap one that I have never used before, so i'd rather brush and have more control. Any input on this!? Thanks in advance

Doesn't matter whether you spray it or brush it, the process is the same.
