Honestly I would rather paint it, I work with Aluminium every day so I'm sick of machining marks lol.
If you do go to polishing it then I can say that Autosol (and a LOT of work) is great for giving a chromed looking finish.
Fantastic design once again, cant wait to see it all assembled.
Its gone in for powdercoating today, soo excited to see how this comes out. Should get it back sometime before the end of the week then i can crack on with the final build.
