Roger skunk is next to impossible to get out of material. I think it just penetrates at the molecular level. Imagine if a house paint worked so good! Nice of the company to send you a replacement! Some battles just aren't worth it, and skunks top the list! I had a jacka$$ of a neighbor/renter next door who partied outside our bedroom windows on his side of the fence , huge bon fire, can tossing into buckets, every night, some nights passed 3a.m. The Police were so tired of coming out they just started to refuse. He was unemployed and an ex fellow with a deep bass voice that sounded like one of those subwoofers in the gang banger cars. It went everywhere including thru my ear plugs. I tried every thing from diplomacy to making noise at 8a.m. while he tried to sleep, nothing would get him to stop. So then a hunting buddy gave me a bottle of skunk oil. It's amazing how fast people go inside when they think a skunk is outside. And they seem to stay inside for weeks! We seemed to have a skunk problem until he moved!
