Electric Spray Guns

airmenair

I did some searching on this topic and didn't really find anything. I'm curious what you all think of electric spray guns? Anyone use them with positive results? I realize air is the preferred way but I don't have the resources right right now to get myself a large 220V air compressor. I took a chance on this Wagner Motocoat sprayer to lay down some SPI epoxy on some floor panels.


It works pretty well I think (coming from an absolute beginner). Not having gravity feed is a minus and the longevity of the parts is questionable. It's all plastic and I don't think there is a way to change tip size. Not even sure what the detail gun's tip size is. However, it does spray a nice, even pattern. It allows for basic adjustments like pattern size/shape, material flow and a really basic air pressure control via a selector (0, 1 or 2).

I figure for just spraying primer, its a pretty decent tool. Am I missing any serious flaws with this? I started with the floors but I think I may use this to spray primer on the body of the car if it holds up ok (and you guys don't poke some big holes in my thinking here :) ). I'm building a driver not a show car.

Looking around the internet, I see there is this electric system from Eastwood that looks like a step up from what I've got. Maybe suitable for shooting the whole car without an air compressor?


What's the biggest drawback to an electric system? Lack of control on air pressure?

I'm pretty new to paint. I'm wading in carefully looking to learn from this community.

Thanks,
Emile
 
Wouldn't think it would/could produce results comparable to a fine tuned air spray system, but haven't tried it so reserve judgement. Keep us informed how things go, with photos. Wishing you the best!
 
Google turbine sprayers or hvlp turbine. Been discussion on them here. You won't get a proper answer from a true professional because they do not use these things, period.
First of all no full time professional shop sprays cars with them. Older or cheap versions can't dissipate the excessive heat they build up like the newer 4 to 6 stage versions or possibly have enough output for certain operations. On the upside, they are the true high velocity low pressure setups and won't put oil in line like piston compressors do. The heat buildup does dissipate moisture pretty well also. They actually are great with epoxy partly because it kicks over slower & actually likes a little heat. Better hvlp units are great for thicker liquids having a pressurizes cup. Many good people do use better versions of these for epoxy. Higher output units can use longer hoses which dissipate more heat. Hoses are large, bulky , & heavy.
I have a Titan 6 stage purchased mainly for commercial paints at work. Does great with epoxy with small tips & great with evercoat g-2 with larger tips. Haven't tried with actual automotive paints, but could do ok for small time use with proper (more expensive) gun AND care using the slowest drying reducers and adding retarder.
Both units posted here are cheap & are kinda like using a harbor freight gun. Both are really designed for small jobs. Also may not even have a small tip set for finer finishing like the better units.. With skill & precautions, you can get a paint job done, but count on spraying enough coats to use additional sanding & buffing skills to smooth out the finish that a cheap gun will give & count on having to overcome possible issues due to nature of these units..
