The original post after removing the pool noodle and green tape:

Afterwards,

The metal tubes were sanded down to bare metal, treated with Metal Ready, and repainted. The PVC tubes were slid over the metal tubes, then filled with expanding foam. If I had it available, I would have painted the metal with POR-15, which is a better product.
Note to all. Do not stick your little finger into the tube. Olive oil can be a bear to clean off so the paint will stick
