You sand it yourself take it to a guitar shop to get it taken apart thent ake it to an autobody shop get it sprayed take it back to the guitar shop and have them re-assmble it.
Or you can do it yourself
Or you cant take it a guitar shop
its either cheap or expensive depening on if u do it or someone else does
Its kinda hard I would guess u need a sprayer and u need to know how to deassmble and reassemble the guitar guys like Aug can do it like nothin.
