diamond cut corrode after so long as its just clear coat over machined alloy, if you did want to keep the diamond cut id advise a bit of wd 40 on the face over winter to stop the road salts eating away at it
hi guys , new to the forum hoping someone out there can help , i have a annoying brake fault message every time i start my car big red warning and flashing handbrake symbol , also abs is lit , ive brought new hub and sensor for rear left (not yet fitted) as on snap on machine it said rear left sensor , would that cause this warning ? thanks
