Review on Black HDPE Plastic Welding Rods by Chad Rosier

I welded my HDPE box to it (and a few screws). I also used them to hold some metal screws in place so I could easily screw in the screws/bolts every time I closed the box. He was NOT trying to be perfectly white. I don't know if I burned it or what but it definitely didn't turn black or anything haha.
