What’s the difference between the XT spray-on and Extreme Wash-in Re-proofer?
It’s basically the same product, but the best method of application depends on the garment. In most cases, the wash-in product give a more even coverage. But if you’re reproofing a garment with a drop lining, such as mesh for example, it’s better to use the spray-on because you only need to reproof the outer material. If you have the option to use either, Granger’s say the wash-in product is better. That way, you treat the whole garment, and it’s less likely you’ll miss a bit.
