Tube painting experiment

[Cwalker935]

Since I have little experience with painting tubes, I decided to conduct an experiment. I turned three gum ball cast blanks made from the same brick with one tube painted black, one white and one silver. Unfortunately, I had a major blow out on the black tube which happens to be my favorite. From left to right black, white and silver.

Might have better luck painting the holes instead of the tubes.

I agree with Harry. Paint the inside of the material after you have drilled it. The white appears to give the best contrast.
