I know this might be oen of those dumb questions. But how can I tell if my 41 has chromed or painted grills? I'm assuming it's chrome, but it's def. peeling off like paint. Should I do any prepping for the stainless steel trim that is rust covered or the outer trim? or should I leave that all to the chromers. I'd like to keep expenses down, but this might not be one of those areas I can do that with.
