Actually forgot to paint the tube on this one, the first one, I painted the tube white. The first is gone, so I can't compare the two. The tube does not show through; but, I will remember to paint the tubes next time.
It is not really opaque, even at the ends where the material is a bit thinner.
I chipped the first one on the end. This one I took down with a skew and then finished with abranet sheets to final diameter. No scratches or chips.
No CA, just novus and polished.
