I need to buy a decent paint spray gun for my machine beautifaification projects. I have a 5 hp compressor and a old gun I have used to spray farm machinery.what are the guns with the paint cup on top?

Let's. Here everyone's thoughts so I can make a worthwhille purchase!!

Thanks scruffy
 
Cups on top are gravity feed, I prefer them as yuo can use all the paint and not suck air into the paint. They can be conventional or HVLP. HVLP is High Volume Low Pressuer, meaning the pressure at the paint cap is typically 7-11 psi. They do a great job with less overspray. I've used the cheap Harbor Freight guns and they are OK for occasional use, but I love my DeVilbiss.
 
I use these, I have them mailed and then if they quit working, in the trash they go. $26.00 including shipping. I have had several throughout the years, some of the epoxies I use will ruin a paint gun quick and to get a Devlbliss or fancy gun rebuilt is more than the new grizzly/harbor freight gun. Tim

The gun you choose should also be suitable for the application - many cheap HVLP and top cup type guns come with a 1.4 mm tip, suitable for finish spraying, but they may not work well with primers, which usually use a 1.8 mm tip. You might look for one that has both caps, if you intend to use any primers or primer surfacer / epoxy primers. Here are a couple examples - I have not used these, but they include both tips.

Here is a set of two guns (includes a small touch up gun) that also has 2 tips.

Check ebay as well. I don't think there is much difference in guns in the low end of the price range. The quality of finish that you get will be more dependent on your ability and experience and the paint and how it is mixed and thinned.
 
I have the harbor freight spray guns in the link posted above. They work fine. They are not devilbiss guns, but for the money, you can't beat them. I'd reccomend setting one gun just for primer and the other just for the fine finish coats. The high build primers are great, but they can clog up a gun with small nozzles. Save your favorite gun for finish paint, and use another one just for primer or any other heavy paint.

I've been painting cars, motorbikes and machinery for the better part of 20 years. I recommend against the very cheapest Chinese guns, and would council you to buy in the middle somewhere between the those and pro quality stuff. I was lucky enough to find a pair of Sata Jet non-HVLP gravity feed guns in new condition for a couple hundred bucks, but for the previous decade I'd used a DeVilbiss Finish Line gun, and had done some very nice work with it.

The current versions are better than that one, and when I needed a smaller touch-up gun a couple years ago I looked to the Finish Line series for that. I'm totally happy with it's performance.

I've used a number of different spray guns from Binks to Harbor Freight my new spray system I've yet to try is a Show Time 90 if you want one of the best this is it a little pricey $699 but that's with a turbine compressor.

For good little spray gun I've been very happy with my Harbor Freight HVLP gun a lot less over spray than the Binks guns and cheap.

It all depends what you want to do with it for quick and dirty I like my cheap gun for cars or better than the Show Time is better.

+ whatever on the Harbor Freight guns. Unless you are doing high quality automotive work, these cheap guns will serve you well. For painting a machine tool you really don't need a quality gun. The main thing is to clean the gun immediately after use. If you don't, even the best gun will be crap in no time.
