I do disagree with your instructor, but...
Just make sure the CHARCOAL NIOSH filters are NEW - that is less than 8 hours of use. Also, when you store the mask, make sure you remove the filter carts and store them in an ait tight baggie. They do deteriorate in air.

3. i have the actual gun clean but the pot has like built up dry primer in there (from SOMEEEONE leaving primer in there for like 3 weeks haha)
whats the best way to clean that.

If it's your gun, and you can't clean with thinner and a kit, go to your local auto paint store and have it professionally cleaned and rebuilt - it's still a better gun than any Harbor Freight gun

4. yeah a painter i know said that my gun would be OK but it def. needs a larger fluid nozzle it has like a 3 inch fan pattern
Not sure what he means - fan width is controlled on the gun. If it's a siphon, the paint output is still a gun control
