It smells like anti freeze...is it?

I’m 99% sure that you can substitute Quality RV antifreeze in place of this stuff. It just needs to be the good stuff that’s $3-6 a gallon. Not the ultra cheap alcohol based stuff. And you are good to go! That’s what all the pumps in a RV use and these sprayers are similar in many ways.

graco pump armour is for storing your machine long term, what exactly is a long term storage? 1 month? 2 months? 3 months?

I use the pump treatment anytime the sprayer is not to be used for a week. I always use it when I finish painting. I have used it for storage longer than 3 months. My sprayer is now 8 years old and I have never had any problems with it.

Does this stuff expire? I have one that is about 5 years old and I was wondering if I can still use it?

Not sure if it expires but I have used my old one up which was 6 years old and my sprayer has been working like a champ even beyond the maintenance schedule

is this for a diaphragm pump too? Or just a piston pump sprayer?

I don't know, but the container says "Storage and Freeze Protection for Airless Pumps."

Reliable Protection for Long Storage

Works great. My sprayer was primed and spraying within seconds after sitting idle for 3–4 months. Pump Armor kept everything protected and ready to go.

Does the job it is made for.

This is the factory recommended product for unit storage. It works like is should as well as I can see. It is just that the unit itself is not a good sprayer, in my opinion, so this product is useless to me.
