Cage match : Air vs. Power Sprayer

Ok,
So i've read a lot about rattle can jobbers. Now I want to do a nice job when I go to paint my Chief when I can... seeing as how it's getting to be cold and winter... who knows? But anywho, what are the pro's and con's between an air spray gun vs. a power sprayer as seen on HarborFreight

I'm planning on doing a semi-gloss so it's got a little shine to it and it looks so fresh and so clean. If I could get some advice on these sprayers that would be great. And I imagine with an air spray gun you need an air compressor? How exactly do they work? Always have air... have to refill... what? I imagine a spray gun is the best way to DIY with best results... Also, when repainting your rig, I take it most people do the inside of door as well? On a scale of 1-10 how hard is doing the insides of the doors?
Thanks in advance!

Mullets ftw!

I don't think that you'll get a power sprayer that's going to handle automotive paints very well.
I'd go HVLP, and that's what I plan on doing when I paint the MJ this spring.
You get much more control over the amount of paint you're putting out. You will need a relatively good air compressor.
If doing it indoors you need to create a paint booth.
I was planning on converting the garage. Put up some plastic, lots of duct tape, a few box fans to pressurize it so dust doesn't come in, furnace filters on the box fans.
lightly wet the floor so dust stays down and have at it.
I would certainly practice with the gun on some stuff first. I think that it's not difficulkt, you just have to learn how to handle it.

The power sprayers tend to heat up a lot. HVLP is the major type used by body shops (less overspray).

What type of paint do you plan on using to make a semi-gloss? House paint?

Power sprayer is for painting a house, I will not look any better that a rattle can job.

89 Daytona : I'm not sure what kind of pain seeing how i've never had to paint a car... that's still something I have to look into. And about this HVLP do you have a link to that? More info etc.. I'm in the learning process.

And when going to pain the door seems. Is it best to take off the inner vinyl of the door on the inside or just tape/bag it off and paint it? I imagine it would look good having a white or black body and open the door to see some bourgandy pain on the inside...Thanks for the advice and tips in advance irate1:

the air gun you posted a link to is hvlp.
Google it, you'll find tons.

Usually the more the HVLP gun costs the better the finish will be... but it also take a lot of practice. The harbor freight guns are good if you only plan on doing this once, if you want to do it more frequently invest a little more in the gun.

Remember, the prep-work is what makes the final job look good.

Thanks for the info guys. Glad you guys actually give advice and not just say to search. Sometimes you just don't find the right answer you are looking for. Also, what would be a good semi-gloss automotive paint? I don't want it super shiny and what not. Just to have a little shine and glisten to it. Flat colors no me gusta! If i'm going to take the time to prep and paint I want it to look sexy. Thanks again!

ive been using a porter cable air gun, itll spray any kind of crappy paint you can throw at it immaculately. as for finish, id depends on hwo you paint it. if you get an air gun make sure you practice up a lot, your first paint job with a full gun will suck, it always does. but with semi-gloss you can sand it with 200 grit and polish a bit for a better finish
