Could anyone tell me a good waterproof spray. I have many beautiful dipes but am having major problems with wicking and leaking. I would love to fix these because most were bought new and I dont feel I am close to getting my moneys worth plus I love the fit of the AIO'S that I have but am aggravated with the wetness. I would love some recommendations for wicking. How long does it last once you spray them and does it really work. any help is appreciated.
