Wonder if anyone can help

Washing the car last weekend notice a flaked off bit on the front N/S caliper. (size of small finger nail)

Trouble is if not painted and sealed it will only get worse....

Call to local dealer or Subaru UK bought no joy - no touch up kits etc for the Gold Brembos. Cant find any contact for Brembo UK, and my Italian is none too hot

I know you can get commercial kits (Foliotech etc) but getting a match for heat resistant paint is not easy. Don't want to go through the hassle of repainting the lot.

Can paint shops mix a shade of caliper paint to the same degree as body shell spec ??

 

Shouldn't this be covered by the warranty?
