I find these little buggers difficult to see in the field and easy to lose. So I tried painting the tops but that wore off quickly. I tried bright red duct tape next but it eventually caused a sticky mess. It was "heavy" too.
My latest attempt is heat shrink tubing. Just about any place that sells electrical or electronic parts stocks it. Most is black though. I found some bright yellow and slightly less bright red at Harbor Freight Tools. I opted for the red as it was $1.99 compared to $4.99. I cut it into 1.5" lengths which covered the entire top and a bit of the straight section. Took me less than 5 minutes to do six stakes. Neat, super easy, light and far more visible.
