[FireSale]

Any tips for a more moderate climate like Washington State? The car is in an unheated garage undergoing minor updates to electrical and interior paint. It's seldom below freezing and if it goes there it's only for a day or two but it is constantly damp all Winter. I currently fire the car at least once a week with water only in the cooling system. I pull it out for a full warm up when I can. Any additive I should have in it?
