I have a rusty rear fire escape which I have refused to paint for about 10 years... i.e. it was galvanised metal and my Mum, God bless her, insisted on painting it wit the end result it needed to be painted on a regular basis...
Anyhow, I think it is in danger of rusting through so I am going to get a drill and a rust attachment on it in the next few days and then I will have to paint it. I am looking for tips for metal painter/primer/rust treatment for it. I am considering Hammerite's straight to rust treatment which comes in colours, comes in big tins and apparently you can thin it and use it with a spray gun (I have never used a spray gun before)
So, any advice on which paint to get and from where? Are there online stockists that I can use as my local DIY store seem to deal in very small tins only? Also, any advice on using a spray gun and are these cheap/expensive tools to buy?
