That said, it’s the middle of winter. I use my hot tub pretty much every single day. Go out and soak when it’s below 10 degrees out even. Great to watch passers by on my rear sidewalk that are bundled to the hilt and I’m out there in a bathing suit.
The link in your first post brings me to ebay but it says your shop doesn’t exist. Did you remove it? I’d like to see the materials you make your balltops with.
