I have a Wagner conversion gun. I have had mixed results with it. I was thinking of buying a hvlp system. Would I see much of a diffrents between these two?

having not used the conversion gun, I can’t speak to that. However, I have had excellent results using the Fuji system I bought 7 or 8 years ago. The model I have is no longer being sold, its replacement is the Q3 gold. It was a pretty penny, but has saved me so much time that I think in the long run it was the right decision (although it did hurt the pocketbook at the time).

I bought mine from Phelps Refinishing. While one of the smaller distributors, Roger Phelps has answered questions for me time and time again and provided some hints on doing things. I certainly wouldn’t hesitate to use him again.

Was there a particular system you were looking at, or just wondered in general about the Wagner vs. actual HVLP systems? I do have a Porter Cable gun, and like you never really found a way to get it to function as well as I had hoped. The good news was it didn’t cost that much. I keep it around, ‘just in case’ ... ;)

I don’t know what a Wagner conversion gun is, a model # or something would help. I have a CA Technologies CPR-G HVLP gun that is fabulous. With the avaible tips and multiple air caps it will spray anything and provide a pro level finish.

Conversion guns have always been my least favorite set up. I’d rather use a straight air compressor gun. But you can tell I’m an HVLP guy! Using warm, dry air makes a world of difference. You’ll have a lot less overspray and more control. I would suggest at least a two stage, but a three stage will spray thicker material and atomize better overall.

I have the Wagner gun and used it for about 7-8 years and actually had very good success with it. Last year I went with a Fiji 4 stage. I do like it a lot better, but there’s a learning curve with it as well. But while I like it better, I can’t say I see a difference in the finish itself. I do see less overspray, and I have a wider variety of viscosity I can spray. I was worried about the warmer air (it actually gets quite warm) maybe drying some of the fast setting finishes (waterbornes, shellac) before they hit the work piece, but I haven’t seen that happen (yet). I do like the Fuji stuff, well made and excellent CS (no offense to Earlex).

Apparently my CA Tech CPR-G is a conversion gun, meaning it runs off a separate air supply. I much prefer using a separate air compressor vs a turbine system. The high air temp of turbines creates yet another variable to deal with, and complicates the spraying/finishing process. No personal experience, but I have read of difficulties with waterborne finishes due to the heat. Also, I understand one should go to the higher end of turbine systems (the cheaper ones just don’t do the job). A gravity feed HVLP is much preferred to a suction cup design. especially with medium and higher viscosity coatings.

I think for the cost of a higher end turbine system, one can get a very nice gun and separate compressor to run it. I have a 120V 2 cyl compressor rated at 5.3 scfm @ 90 psig, and the only time I have needed to wait was doing a large (3’x 7’) table top, I just took a little more time between passes. My gun is rated 6-10 cfm. The compressor was ~$400 and the gun with 3M PPS (love this system) ~$450 about 4 years ago. For me, a compressor is required for the shop anyway, so when the previous one went belly up, it cost me maybe another $100 for the larger compressor.

Finish Systems (http://www.finishsystems.com/sprayguns.html) has been great to do business with. They carry many brands of guns, are very knowledgeable about wood finishing and overall system setup and compressor size, and very competitive with price.
