Looking for some input on acceptable level of rust, if there is such a thing, on this grate. It was left out over winter at the Vets Club and I was hoping to do some chickens on it for the annual picnic sometime in August. A bud lent me a side grinder with wire wheel and it did a great job on the surface but, as always, in between the holes there is some rust that cannot be gotten off with just grinding. I suppose one could find more and spot weld it on etc but money is always tight as is finding someone to do it. Here's the pic....I was thinking a good oiling of course and a burn in with a bag of cheap leg quarters to season it up a little. Looking for some honest input...could this be used or best to start over?? This is the pit and what similar grates looked like before and the large one after I cleaned it up.
