Winters here in the Pacific NW are not too cold but it's constantly wet and damp. Snow is minimal and if it does snow, it doesn't stick more than a few days, almost always washed away by the eventual rain. What's a good (read: durable) tire dressing for this type of climate? And how long do you think it will last in constant wet weather? I've never bothered with tire dressings during these horrid months but thought I'd start this year. Or is this a hopeless case? In the drier months, I've used
Meg's Endurance Gel,
Wolfgang Tire Gel and 303 sometimes. They've been all okay, lasting at most 2 weeks in dry weather.
