In the past I have always used POR 15 and been very happy with the results. Being here in Australia I have been thinking of getting some more. I was down bunnings the other day and I noticed they sell a rust converter product called Ranex Rustbuster.
I like the idea of this as I eant to be able to buy a product over the counter. Has anyone used this and if so how have you found it, is it any good?
