Hi I have just finished burning off 40 years of paint from my front gates, and am down to the metal and rust. Any ideas please, on what is best to do before I paint again, to get a few more years out of them. many thanks
With hammerite you need to put it straight onto bare metal for it to work properly, Hammerite reacts with the metal, and also reacts with rust, if you red oxide first you will lose this reaction and the hammerite will just become rather expensive paint, which isnt doing much but looking good.
