I did it at about that age to a 1300 Marina de-luxe in baby diarrhoea brown or Laguina Beige as BL named it.
just give them a wire brush and spray them with high temp caliper paint should do the job!!
Ohh and do the pilot sport 5s work nice on the x power??
going to use them at some point was just wondering on your thoughts over the stock turanzas ??
