What does 4% look like if using an x-jet? (Which orifice?)

i used the x jet for those pics. refer to the proportioner chart to find out what tip you need since it’s different depending on your GPM

Never use a backpack sprayer for applying SH. If your backpack sprayer happens to leak this leaking SH will down your back and down your crack causing your skin to burn resulting in a lot of PAIN!

I don’t have any meaningful knowledge of xjet orifice sizing, plenty on here that use them.
