Lots of shiny bits

I've been looking into how to make the rough looking donor parts into nice shiny new looking parts and it seems one way to go is sand blasting and then zinc plating or powder coating. 

Here are a couple of companies near me that do this:

Sand Blasting & Powder Coating http://www.moransandblasting.co.uk/

Zinc Plating http://www.silchrome.co.uk/zincplating.html

Powder Coating https://www.facebook.com/pages/Thorp-Arch-Powder-coating/132041663618921

There are also some DIY options

Powder Coating http://www.electrostaticmagic.co.uk/

I haven't worked out costs yet to see which is the best option. I'll update this when I do.

UPDATE: I decided to use POR15 and rebuild the parts myself. See later posts for how I achieved this.
