I'm new to this so please excuse the dumbness of my questions. My new home has a very ugly metal shed which I want to paint. The roof has a lot of superficial rust and there is also superficial rust on the doors. The rest is pretty good. I've spent hours online trying to buy oil-based paint which will last but can't find any other than silver or black, neither of which I want. It seems there is a lot of paint and primer available in US but not here. There is all kinds of advice and videos but I can't find where to buy what is advised here in UK. I'd like to strip off the superficial rust. Prepare with a suitable anti-rust primer/use suitable two in one paint if available. Paint in a colour, maybe blue or white. I'd like to be sure the paint will not lift off. Paint I used in Bulgaria which was supposedly OK for metal just lifted off within a year. I'd like a proper external, metal paint which is going to adhere, not lift off, and will not require repainting for a very long time. I don't have any equipment except a ladder and brushes so need to do all of this by hand. Be very grateful for advice. Thanks for reading. Keep safe.
