In there past there was some discussion on paint spraying systems for people without large compressors. What were the systems called and any recommendations?

thanks

The size of the compressor determines how much area you can spray at once. You could paint parts all day using only a smudgepot compressor. Now if you were to paint something the size of a car hood you would run out of air before you could do it and paint is something you can't start and stop. Once you start painting an area you have to spray continuously from one side to the other. If you stop and start again it will leave a line. It doesn't take a huge compressor to spray paint. If you got one at least 4.0 scfm at 40psi you should be able to paint anything. If you kept it up all day you might have to stop and let the compressor cool but it would deliver enough air. Except for some automotive paints I like the Harbor Freight #97855 sprayer. It doesn't atomize metallic paints very well. You have to work at it to get results. Other than that it works fine. I've painted two tractors, my jeep and some of the parts of an old oldsmobile with it. You can't tell the difference between the trunk lid I did and the front fender and hood a professional body shop did.

OP : What are you wanting to paint? I think what you are alluding to is "turbine sprayers" and I'd leave these to woodworkers if I were you.

IMO saying a 4 cfm will do "anything" is just setting someone up for failure or at a minimum, disappointment. I could see getting away with this for a small job, with an auxilliary tank, and/or doing extremely small batches. I don't know if I'd be brave enough to start in on a motorcycle tank with 4 cfm to be honest. 4 cfm @ 40 psi...That's getting down into pancake compressor territory.

Guys really like the HF guns, but I find that the cheap guns tend to build up paint on the inside and are just over-all more fidgety.

If you are painting any decent sized batch of parts or body panels, you need a gun that can keep you moving. Guns that can keep you moving use a good amount of air. There are some really good "HTE" guns that are labeled in the 8-10 cfm range.

Stay away from HVLP for sure.

There is a compressor pretty much every home center and hardware store sells with a Sanborn pump on it for like $450 or less if you can find coupons, etc. I almost always recommend this one for a first compressor. It is the best investment you can make in a home shop IMO. Nothing beats air tools.

Well I am not a painter by any stretch of the imagination, blind in one eye and the good one is going south. I have compressors and paint guns but I wanted to try this HVLP a few years back
for different small projects . I brought this Fuji with all the different needles for different thickness of paint, everything from lacquer to latex. So when I was rebuilding this tractor I thought I would try this gun and all things considered it turned out ok for a work tractor. I had the Wife paint the scripts,I figure if she can do Nails for women without getting polish all over their fingers she could do this.
I shake like an old dog crapin peach pits.

That one looks pretty versatile. Most of the cup guns won't spray latex because the paint is so thick but that one pressurizes the cup. That is really important for latex. I don't care for the mason jar type cup on it though. It's similar to harbor freight purple guns. The least amount of paint that gets in the treads will glue it to the gun where you have to fight to get the cup off. I have one of the HF purple guns but never use it for that reason.
