I re-sprayed my sunburst P bass copy last year using a Fiesta Red aerosol from Manchester Guitar Tech.
I didn't rub down back tt the wood, just took off the gloss & then gave it a covering of Halfords primer before several coats of FR at several days interval.
Take your time & gently rub down between coats. Finish off several times with a rubbing compound before a coupe of layers of clear lacquer (Halfords again!).
I haven't got a high gloss finish but I'm happy with it & it looks great on stage & matches the proper FR Strats the other guys on the band use.
