I do not recomend powdercoating the chassis. You will eventually scratch the frame at the bottom hitting some road debris or when entering driveways. You will sometime also lose brake fluid or clutch fluid. Your powdercoat will be up in a mess and not be easy to touch up.
Get a good paint job with primer and that is ok. I have had to retouch my frame several times, especially after purging the clutch master cylinder.
