I just found this product they call ultra ever dry and I thiught it was pretty interesting. If u havent ever heard of it than its definately worth looking into! Bassically its a two part solution that u spray onto a surface and it creates a hydrophobic coating that will repel water and mud and bassically anything with water in it. Theres a youtube video of it and it seems to work incredibly. So my question is.... u could theoretically spray this stuff on ur huntin rifle and never shudder when u get caught in a rain storm? And rust should be a thing of the past?
