Hello
I used the primos silver spray on my rubber boots. The boots were about 9 months old and I had walked on a wide beaten down trail to get to my stand. There was no vegetation to rub against and I try to be scent free as possible. But a nice yearling buck came walking along and instantly became nervous once hitting my track. He didn't stick around long. The wind was in my favor and I have a lot of nice whitetail bucks to my credit and his reaction is what I would've expected from a mature buck had I walked the trail in tennis shoes. Either the boots still had that new rubber smell (which I couldn't smell) or the silver spray really bothered him. It may have been a fluke, but I haven't used it since.
