llllllllllllllll
I’d go with rust olium al the way ,or check on powder coat
what color is the vehicle your putting them on?
I took mine apart to paint them but Leslie power chambers are a pain to take apart. You could always paint them together and replace the bolts with shiny new ones. I would be VERY careful painting the bells though, don’t wanna get any paint on the diaphragm. I just painted mine with duplicolor gloss black. It’s automotive paint. I had a spray can primer underneath. The black was sprayed with a gun. You can see the shine of it on my thread about Leslies. Kinda hard to tell from a cell cam though lol Hope this helps!
