A Good Sprayer

Got this in this AM and it works great. Fill it with whatever you want to spray (not paint), pressurize to 100psi and coat everything with the spray. No more Home Depot sprayers that last 30 minutes. Made in the USA too.

Fill only with stuff that does not oxidise, ask me how I found out.
I used a small one to spray cooking oil years back when all these aerosolized oils came out and the nozzle became blocked frequently due to oxidisation of the oil. BTW vegetable oils make great cheap anti-rust storage coatings although some can leave a stain on bright metal and they need Turpentine or White Spirits to remove.

I used to use smaller cans of that for various solvents when I worked on industrial equipment. I forget what it was, but one fluid turned solid when I pressurized it. A surprising reaction!
