Hey OG, there is a company that makes an attachment for spray cans for spray painting things, that essentially turns the can into a spray gun. Trigger and all. It's extremely nice and convenient. I don't recall the company name, but I have one at home and will get it for you later on today. It's only like 7$.
Found it, tbh it's cheaply made, but I went through 6 cans and it till isn't broken. It should attach to any spray paint can. Don't delay. I know you have 7$.
