Do you live in Rome or just visiting? ebay.it has 8 results (international) that will ship to you, hope this helps! I'm vslling Casio tomorrow for a sales enquiry so I'll ask them about this as well!
Strange . . . I've just posted about using IPA and Maguires Stage 1 body polish!! NickyC will know Maguires very well I think!
I've used the stage one stuff on my stainless ones for years and they've never tarnished!
IPA is fine because of its alcohol purity, it also evaporates extremely quickly without leaving a cack residue!!
I use Maguires body polish stage 1 on mine, it works a blessing on the Land Rover and equally as well with stainless steel!!
