Powder coating is quite reasonable I got all my rear suspension parts done for £70 and that included the fuel pump bracket. It cost the same amount to have them blasted though so was £140 all in job done, that was just black however it does cost more for colors. I also phoned my local hire tools place and they can rent me a compressor for £30 a day so all I would need is the spray gun I guess.. And the paint of course.
