if u dont sand it, and just paint over it.. its also possible.. but by then, your guitar body would be thick of paint.. some say it makes the guitar resonate lesser.. this is wat i did in terms of steps...
1 - sand down the body of the guitar using sandpaper(60-80 grit). sanding machine is recommended.
2- after the body is sanded down and u can see the complete wood, sand it again using a higher grit like 240-360 to make it smooth...
3 - now hang the guitar using a bendable wire hanger, and spray the guitar with sanding sealer, etc..
4 - spray a 1st coat of paint on it. not too thick, then wait maybe 2-3 days for it to really dry.
5 - check the body. if any wood grain risesand effect the finished paint of the body, sand it down again using 1200-2000 grit sandpaper.
6 - spray paint the body again. repeat if necessary. maybe 3-4 coating depend on personal preferences.
7 - Finish the body off using clear coat lacquer or satin clear lacquer.
8 - the end.
this is approximately the steps that i've done... but then again im no expert on this. its just that i am a bit handy with tools and as fate would have it, i am in the electronic/electrical/technical line of work. this is just my experience... was a tiring and tedious project, only recommended if u have the time and patience. be prepared to sacrifice some time if u going to do this but it was worth it to me to see the end job.. i found the steps and tutorial from the net.. cant recall the website.. i just got a strat guitar body recently. its sunburst also.. im also thinking of stripping it and doing it again.. maybe paint it cherry sunburst or red... at least this is what im thinking... maybe i will take some pics and write a step by step tutorial.... what u guys think??? :?:
