So basically when it comes to painting all i have ever used was just a basic rattle can and a paint brush. I am looking into the market for a good spray gun thats around 50 bucks. also i need an air compressor and was wondering what a good beginner setup would be as i want to paint my next projects with a paint gun and also maybe a cheap air brush. Any suggestion or info would be extremely helpful!!! Also i need some info on what paint to use as well.

I was looking at this setup...

Compressor:

Gun:
http://www.harborfreight.com/air-to...ow-pressure-gravity-feed-spray-gun-66222.html

Air Hose:

Air Brush:

Any suggestions or comments are greatly appreciated!!

I hadn't commented yet because I'm still trying to figure out what I think of that gun. A conventional HVLP gun requires a specialty HVLP air source. This source is traditionally a turbine (fan) and features a fairly large diameter hose to accomplish the high volume at low pressure. Picture a hair dryer connected to a 3/4" or 1" hose. Doesn't make a lot of pressure, but plenty o' volume.

The gun's specs are throwing me off- 15-45psi? 45psi is not what I would consider HVLP. And look at the flow rate? Well beyond what the compressor can keep up with. With that large tank, you'll be able to go for a bit, then you'll have to pause for a coffee break while the tank recovers.

Back to the gun- I've seen "HVLP" guns like this before, but have never used one- so I don't know what to tell you. I think this particular breed is a "poser" as far as HVLP goes, but that aside, it will very likely work for your purposes. Pictured below is a "real" HVLP setup. Note the turbine unit (instead of a compressor), and the large diameter hose and fittings.

Iv only sprayed face shovel buckets useing a similar setup to the toystorys pic
Exept the aircompressor is the size of a car and puts out 120 psi
I can't speak of the skill as bucket painting requires none

But like toystory said I'd say u need the volume
We usually use 1/2 air line and the slightest kink in the line stops the whole operation

Those guns that u have selected work ok but they are mighty slow and Iv only seen them for touch up jobs

Just thought I would share my experience-
I have done a little bit of spraying. I used a 5 gallon compressor (2.5hp, 9.5cfm) which cost £120, and came with a free cheap paint sprayer. Worked OK for what I was doing.
However, if you are going to use it a lot, I would reccomend a better one than what I have, and make sure you have the correct thinners for the paint to spray through it afterwards to clean it off.

Any recommendations on a good sprayer that can be used with the compressor shown above. I would like to spray candy colors too... Not sure if that matters though

You're using an HVLP for agricultural equipment? Wow- jeez! Normally, HVLP is reserved for fine finishing like cabinetry and cars. I've done both.

Seeing you're local.. Start looking here.
http://www.estatesales.net/estate-sales/IL/Chicago.aspx

I see dozens of U.S. made ones within the past 6 months at various sales. I would start going to these. You can find 100% American made tools and equipment. I can only go on Saturdays to various close to home ones but, the first day they open (usually thursday) is the best. You're gonna find tools at pennys on the dollar. Of course you'll find Chinese crap at those too. Some of the HF ones can do a pretty decent job with paint from what I've gathered . I HAVE NOT tried any of these or U.S. made ones. Just sayin'

Well 10 ft mining buckets

It may not be the same thing but it looks the same

Crank it right up and it puts out a 2 ft spray area

Some of that Chinese stuff is ok

I agree with you on "some of that chinese stuff is o.k."

There are alternatives without dropping big coin. Sometimes ChiCom sometimes used domestic made. Hf tools do have thier place. I prefer them NOT to be in my Hf cabinet. Yes I'm serious. I have one of those 41" combo set-ups. They are great imho. I have mine packed with tools. 95% are domestic made. I can't spend the coin on a Snap On. The money isn't the issue the 3 daughters are. If you buy one please fill us in on the good , bad and ugly of it. I'll never buy one because I don't paint. If I can't rattle can it I'll leave it bare metal.

Doesn't make a lot of pressure, but plenty o' volume.

The HV in HVLP is referring to the paint volume, not the air volume. Because it's a gravity fed gun, you get a faster flow rate than a suction fed gun while using very low air pressure.

Suction guns suck (no pun intended); they're big & cumbersome, they require more air pressure, they don't have a consistent flow rate & they're a pita to clean. If someone offered me 5 suction guns & 1 gravity gun, I'd take the gravity gun.

The gun's specs are throwing me off- 15-45psi? 45psi is not what I would consider HVLP. And look at the flow rate? Well beyond what the compressor can keep up with. With that large tank, you'll be able to go for a bit, then you'll have to pause for a coffee break while the tank recovers.

Again, I disagree. I've been using a similar setup for about 5 years (2.5hp with 10 gal tank, 114 lpm FAD) & the only time I run out of air pressure is when I'm sandblasting, never while painting.

This setup will be fine. I'm goint to make 2 suggestions:
1. Take the regulator off the gun &, if it doesn't have one, put it on the compressor. The gun already has a regulator, the knob beside the dial reg.
2. Before you use it, strip the gun to pieces, clean it & put it back together. There's 2 reasons for this; 1. you get to know how it works & 2. you know you can. I had a problem with a gun like this; everything was glued together. I couldn't strip it down to clean it thoroughly so, after a year, it went in the bin.

Don't forget about fittings...

I would avoid an oil-less compressor and go for one with a good oiled pump, it will last much longer and run better. Also, that paint gun is a good starter, but don't pay $35 for it, wait for a sale or coupon and get it for $10-$15.

I havnt painted my frame yet, but ive primered areas of my old car after body work, and heres what i use - 8 gallon compressor and a HVLP gun from homedepot. Works fine for diy jobs, just make sure you clean the gun right after you finish spraying otherwise its a pita to get it cleaned when paint dries. You'll need at least a 5 gallon compressor otherwise you'll have to wait every minute or so for the tank to fill.

heres what i use

i got it when it was on sale though. lol

The HV in HVLP is referring to the paint volume, not the air volume.

Stolen from Wiki:

"HVLP (High Volume Low Pressure)
This is similar to a conventional spray gun using a compressor to supply the air, but the spray gun itself requires a lower pressure (LP). A higher volume (HV) of air is used to aerosolise and propel the paint at lower air pressure. The result is a higher proportion of paint reaching the target surface with reduced overspray, materials consumption, and air pollution. A regulator is often required so that the air pressure from a conventional compressor can be lowered for the HVLP spray gun. Alternatively a turbine unit (commonly containing a vacuum cleaner derived motor) can be used to propel the air without the need for an air line.
A rule of thumb puts two thirds of the coating on the substrate and one third in the air. True HVLP guns use 8–20 cfm (13.6–34 m3/hr), and an industrial compressor with a minimum of 5 horsepower (3.7 kW) output is required. HVLP spray systems are used in the automotive, marine, architectural coating, furniture finishing, scenic painting and cosmetic industries."
http://en.wikipedia.org/wiki/Spray_painting

HVLP stands for High Volume Low Pressure, and does indeed refer to the air supply requirements. The reason I'm not nuts about the above-mentioned gun style is that it does not meet the true definition of HVLP in my mind. You are feeding the gun High Pressure and using a regulator at the gun to reduce the pressure. In doing so, the volume is also being restricted. In a true HVLP system (turbine), the air supply remains at the same volume and pressure all the way from the pump to the spray tip. It lays the paint out very gently. I am NOT saying the above system doesn't work, I'm just choking on the definition.

Now- If you were to take the regulator off the gun as suggested above, and use the regulator on the compressor, what you're left with is very simply a conventional spray gun.

I've seen some pretty good paint jobs with the harbor freight hvlp gun. Also check out devilbiss, they have a three or two gun kit for just over a 100.00 thats good. I agree you don't need the biggest compressor in the world to do what you want. I suggest getting a 20gal used one over the harbor freight one though. Heck i have a new china craftsman compressor that the aluminum air hose broke after a month or so. I'd rather buy a used good brand compressor than a new cheap one.

Ok, so this gun is not a true HVLP gun.

This type of gun is referred to as HVLP as a comparison to a suction fed spray gun which reqires more air pressure & delivers less paint. This gun will dribble paint if you squeeze the trigger with no air line attached.

Now- If you were to take the regulator off the gun as suggested above, and use the regulator on the compressor, what you're left with is very simply a conventional spray gun.

Exactly. The gun itself is fitted with a regulator so the reg that has been added is unneccessary.
