I've scored some used Cliplock roofing that I intend to replace my shed roof with.
There is some significant surface rust in on of the two channels on each length, and my process so far has been to run over it with a rotary wire brush in a drill, pressure wash it and then coat with Penetrol.
I'm wondering how necessary it is to do the wire brushing, as it adds a significant step in the treatment of each length, and is rather noisy for the neighbours. Just now I went straight to pressure washing on one length without brushing it, and there is no loose rust, and it doesn't stain my finger when I rub it.
What say the brains trust please? Continue wire brushing or just proceed straight to the pressure wash?
