Thanks!
Yes, an air compressor and sandblaster would be very useful tools, but I have neither, and don't want to invest too much if I can do it by hand too. My time doesn't cost me anything, and being a student, I don't make any money either. So I rather spend a day extra cleaning everything by hand if that means that I can buy another part for my Europa.
The easy way would be to have it powder coated, they sandblast everything before they powder coat it. Two birds with one stone, but not the satisfaction of knowing that you've all done it yourself (and saving quite a bit of money doing so).
