I have been following Eddies paint process. I am about to purchase some sprayguns. I currently have a 2HP, 20 Gallon Campbell Hausfeld compressor that is rated at 5.7CFM @ 90PSI.

On the cover of the new Eastwood catalog they have a kit of Devilbiss that includes two HVLP gravity feed guns.

Could my compressor drive these guns? (there are no rating listed for them).

I only intend to take it slow. ie do a section at a time. Initially I will be doing the door jams and inside of the door in prep for new weather strip. When I get the guts I want to do the whole car but that is a few years away.

What drier / water remover do you use. I have a harbor freight setup but there is a lot of moisture in Florida.

TIA,

Pete

 

You should have no probelm with an HVLP High Volume Low Pressure

 

I would at least have a 5hp compressor before I tried spraying. I'm spraying mine with an old 6hp 60 gal upright and when I say old I mean old, it's hard to find the compressor thru the rust but it worked very well and kept up with my gun completly. You can find used compressors at yard sales and flea markets on the cheap.

Even with the HVLP gun a little more pressure is a good thing as it breaks up the paint better. It was easier for me to use a little more pressure and it still didn't hardly put out and overspray.

I looked at the Eastwood site before I bought mine. The Devellvis, I'm sure is a far better gun but I don't plan on doing this for a living. I just needed a gun that would work for me a few times. If it wears out, no problem I'll get another one and still be ahead of the game. What really convinced was what Lars wrote about the cheaper guns, it really made up my mind. I have a link to his article on the first page of my post. I believe he really knows what he is talking about.

As far as the water filter, I just got one from Home Depot. I think it was around $30. I didn't get any water spots in my paint so I'm assuming it worked pretty good. We have as much or more humidity in Ga as yall do. I know when I go to Fl on vacation my sinus really clears up

Oh and by the way, Don't be afraid to paint your own car. It is nowhere near as bad as I thought it would be. I'm enjoying it and having a lot of fun learning new things.

i seriously doubt it....they are "low pressure" guns at the output but require a serious volume of air to make work....call the east wood tech desk they can tell you what SCFM is necessary

 

Bob,

I figured they would be close to 10CFM or so at a lower pressure. I am going to give Eastwoods a call.

Eddie,

I would love to paint my car. It actually looks pretty good right now. I am about to hack around my passenger door to get the fit right so I will need to do some repairs. I will cut my teeth with the door and depending on how good it turns our move onto the rest of the car. I am in a rental house right now and don't have a yard where I can spray. My compressor is only a couple of years old and I am reluctant to buy a big compressor as I have to ship it back to OZ at christmas. I guess the big compressor and the full paint job can wait till next year.

Lars is definitely on the money with the paint process.I have read that paper 3-4 times. If you ever get a chance to meet him do it. He is one of the most knowledgable car guys I have ever met and he likes to share his knowledge over a cold beer. Lars came down and tuned for us last year. I didn't know I had a V8 under the hood until Lars tuned it. We (car guys) are fortunate he has written all his knowledge on the internet for us to use.

Let you know what Eastwoods say.

Went to the Eastwoods web site. More info then the catalog.
Here are the specs for the guns:

Spray Gun Specifications
30 psi inlet pressures delivers 10 psi air cap pressure at 13 cfm air volume. Air inlet: 1/4"NPS
Touch Up Spray Gun Specifications
30 psi air cap pressure at 8 cfm air volume. Air inlet:1/4"NPS

My compressor just cannot provide enough CFM.

 

yeah thats what i thought.....sorry.....when i upgraded my compressor i went with a huge one to have the SCFM for this and a sandblast cabinet....

 

I've been checking out these driers/filters/lubricators/regulators. Each has a different purpose and I guess you could buy a string of these things for your compressor...like options.

Anyone know of good sources to read up on when to use what I would appreciate it.

 

i use a $125 model in my garage that is excellent for moisture its made by rti reading technologies incorporated stealth model.My old ones never worked like this one does you need at least 25 feet of line before the filter then hook your hose to it.I just run a extra hose down my wall then the filter then another 25 feet of air hose to the gun.I have a few different guns iuse anywhere form a develbis jga siphon gun,finishline 2 ,matco gravity fed(made by sharp)and my favorite is my snap on hvlp gravity fed ,i just rebuilt it and it works the best ive ever had,it cost me over 400$ 10 years ago.

 

Good luck with your paint project.
There's always lots of good paint related information on the CorvetteForum!

AutoBody101.com is another useful discussion forum for paint related stuff.

 

Thanks.

I am going to practice on my beater (91 Mercury Tracer) And tehn move to the Vette.

I am going to buy the Eastwood kit. I have a friend with a 1 Acre backyard and a big compressor so we are going to give it a shot.

I will be sure to post pictures.

Do yourself a favor and buy some disposable moisture separators/filters that attach to your gun. They are cheap insurance against water and oil in the lines. Also, a pressure regulator at the gun is helpful to be sure you maintain adequate/consistant pressure at the gun. You'd be amazed at how much pressure drop there is in the airline while spraying. The consistency in pressure is important for getting metallics evenly applied.
