This is the original bow I started with, I spent a month trying to determine what kind of pipe was used to make the bow. No one seemed to recognize it. I bought and tried several different kinds of pipe, until I discovered that it was blue 3/4 inch PEX pipe. I got white thinking I could paint it. PEX pipe doesn’t paint well. You will spend a lot of time getting the shine off the exterior of the pipe before the paint will even dream of sticking. Save yourself some trouble, and buy red or blue pipe, that way the color is taken care of.
