Just to say you were right about CRN, shocking delivery times, they seem to blame it on the zinc coating......as it has to go to the "platers" be good if they explained that to you when buying! I have had to pay an extra £15 for saturday delivery as the car is booked in Monday!
I havn't done anything with the carriers, just kinda creamy silver colour so going to let the dirt buikld up onn them i think!
