I've always had a few tins of Hammerite knocking around in different colour for the odd touch up or painting of bare metal but I'm running a bit low. I know it's not what it used to be but is there anything else out there that is as simple to use but lasts longer / gets a better finish? Ideally straight to metal but I guess a can of primer and various top coats would be ok - as long as they last once opened. I don't tend to go through much and nothing worse than finding 3/4 of a tin that's gone hard when you need some!
