hi i have a mini paddington in silver and the handles were becoming orange... i bought last month a particular metallic silver spray for leather ... the effect was perfect and the bag returned like newMy aubergine paddy has experienced colour loss, particularly underneath the handles and on the edges of bag. This has revealed metallic silver underneath but I think it looks quite nice, given that the hardware is also silver!
I've sent back a gold paddy and another aubergine paddy to NAP before because they arrived with noticeable colour loss. The gold had faded away in parts to reveal areas that were both black and red in colour!
