Going out on a limb here - I need to waterproof some boots. There seem to be any number of products on the market that all seem to do the same thing (more or less). They range from rub in pastes/waxes/oils to straight beeswax to aerosol sprays that you simply spray on (seems to be the easiest), etc. Anyone have any real world experience with any of these? There is Nikwax, Aquaseal, Snoseal, All Dri, Kiwi products, Chelsea, etc. and I really can't find anything that indicates one is any better than the other. This would be in conjunction with rain covers, I'm just looking for something that will add a layer of protection in light to moderate rain until I can get covers on. Thanks!
