Hi VinnieL
i hadn’t considered any of your thoughts about corrosion and oxidation. I haven’t had any issues in the past or at least any that I am aware of. I tend to shot blasts wipe down with thinners then etch prime straight away and then two or three coats of paint. I am by far from a painting expert it took several years for me to build up enough courage to paint my Sweetpea loco so I would also be very interested in views of people with experience in this discipline.
