I fitted some chrome washer jet caps on GBMINI today – the black ones were graying from wax, and Indi Blue looks much better with chrome. I bought them from CooperTuning, a german company – the parts arrived in about a week so no problems with shipping. The price with shipping is around $30. They fit over the black washer jet and fastens with double sided tape – it does not quite fit down to the hood, but looks fine unless you get really close!
