hey..does this process work for guitar bodies? i was thinking of dying my alder strat body...will it be water proof after i polish it? what should i polish it with?
If you mean like a guitar you bought already... well, from what I've seen of guitars, I think they're already lacquered before being sold. You can try dyeing it, but I bet you apply the dye onto the guitar, later you wipe it off the guitar still not dyed, because the lacquer is there to protect the guitar. So... you'll have to carefully sand off the lacquer, then dye it, then re-lacquer it. If you haven't done it before, but really want to get it refinished, I recommend you find someone really experienced with woodwork to help.
Polishing won't make it waterproof, lacquering/clearcoating/etc. will. I don't know what you should use on guitar. I just use regular wood varnish on my drums.
Actually, just the way I see it, you might want to use wax on your guitar. I don't have anything to back this up, but usually when I see nice guitars, I think that the wood would look good with wax.
Just wanted to know, how much did the laquer and wood dye cost altogether?
One bottle of dye, as seen in the photo (I forgot the exact volume of the bottle) was enough to cover five toms, two bass drums, a few pairs of sticks. It costed about $22 I think. I used total of two cans of lacquer (giving a few coats) on the above mentioned drums. Each can was about $25 I think.
Since I've used them up already, and thrown away the can, I can't check the volume. But! If you go to homefix DIY and see the prices roughly around what I said, then that's probably the right size. Also you read what it says on the can, they'll tell you about how much surface area it can cover. Make your measurements, do some math and figure out how many cans you need.
