I bought 3 water based wood stains: blue, green and yellow. I also bought a piece of raw maple (in wich i try the diferent mixs til I came up with the right colour, wich looked almost green

).
I used a sponge to aply the stain. I apllied to the whole guitar. But in the back and the neck I had to aply several times because the original stain was almost completely worn off.
Then finaly I aplied a polyurethane natural finish. Its not a clearcoat, but a gentle satinated finish that allows the wood grain to show. Its mate, and is looks very smooth, like an oil finished body.
I dont hace adigital camera right now, but Ill have one next week.
I also replaced the knobs with metal ones, wich I brushed to match the pickguard.
In www. projectguitar.com there is en explanation of the process, in wich I based my work.
