As luck would have it, I have a nice selection of products from those nice people at Grangers, and it's time to reproof my bike and ski kit.
However, which is best? Wash in, or spray on? To date, I've used spray on, but now I've got both, I just wondered if there was a concensus on which is more effective? Fixed fabrics, by the way (event, Gore, HiVent and Eider's own stuff)
