Thanks guys
I was getting epidural shots. They work great until they stop working (that's why the surgery). I still get them - once every three months for my neck which affects my right arm.
I had some sand I purchased from Hobby Lobby a while back. I spread wallboard putty over the seam in a small section and poured the sand over it. It worked good except the sand is the wrong color. I have an email into Woodland Scenics asking if there is a fine ballast or some other product that has the same color as the sand mats.
