The zed is an embarrassing state from several motorway journeys and I'm considering whether it's worth getting him valeted properly before winter or not? ideally I'd like to get some scratches buffed (machine polished?) out too (and wheel refurbed but one thing at a time)..considering that he is a daily driver (~15m) and kept on driveway (though I have a cover now) is it futile getting him spiffed up only to wrecked by the weather after 1hr? OR wait till spring?
