Very narrow spray pattern
A 1" pvc sched. 40 pipe cap is a perfect friction fit on the end of the Harbor Freight gun. 3/8 inch diameter hole and a cut down electrode (just leave a little thread for future use) makes a pretty perfect narrow flow for running up and down between rows of bullets.

Alternate time and temp for HF matte black
I did a test with the HF matte black because my wife found me a convection oven at Goodwill for $12.99. When she brought it home, come to find out that you cannot control the temp only the time. Everything is preset. I verified the temps with my casting thermometer. Pizza is 425 on the dot, bake is 350 on the dot. I figured no need to measure broil as it should be 500+. So using the HF matte black I put a run of 9mm 124 TL in on the BAKE cycle (350 deg.) for 25 minutes, pulled them out, dropped them into water. A couple hours later I pulled a couple samples, and smashed them with a hammer. Not a flake of PC came off. I smashed one straight top to bottom and the other was laying on the side.
Shot them last weekend and all were very accurate and no leading, no PC in the barrell. So it appears in my experiance that a lower temp for a little longer time will cure the HF matte black without issue.
