I came across this yesterday and thought it may help anyone who is contemplating reviving an old Colorbond roof or touching up some scratches etc.
We have had limited success with touch-up spray cans when we have roofed a house and some other knuckleheads like antenna guys have got up there later and scratched the beejeezus out of the sheeting.
This is just the official tech bulletin put out by Bluescope Steel and is in no way the definitive guide ( it is actually somewhat limited ).
Anyone else out there with hints or tips or a product especially for touching up scratches , post them up here.
