@#$%^ I hate it when I write a post, hit post and I mistyped my password or something, go "back" and everything I typed is gone.

Are HVLP paint guns worth the expense over conventional guns for a home hobbyist who will likely only use the gun a few times? I'm going to try out painting on my old F-150, and if it turns out well, might actually go for the mustang paint job. Also, anybody ever take a class at a local tech school for painting? I'd consider that too to learn right before messing anything up.

Also, some paint guns require a certain cfm at a certain psi. If my compressor puts out 6.5 cfm at 100 psi, will it put out more cfm at 50 psi, or is it always 6.5 cfm. And if it does change cfm, how do I measure cfm? Obvously psi is on the guage.

Taking a night class is a great idea. You can even get access to better tools than you'd have at home.

The new HVLP guns are great, but whether they are worth the investment for one time use is up to you.

I have been painting at home for more years than I'd like to admit. I still use my old faithfull suction cup binks and I get good results but the lure of the hvlp guns have me tempted too. From what I understand, you get what you pay for. In other words the cheap ones are junk...lol Anyway if you do buy an hvlp gun I have heard the gravity feed guns are better than the suction models. Heres a thought, take a class and paint your truck for practice. They will supply all the tools and advice you need.
Good Luck
John

Sometimes, while you are at that blank page, you can hit 'reload' and it will all come back.

Sometimes, if it is a really long post, it pays to write it in 'word' or some other program, then cut-n-paste it into the MM page. ...not that I've taken my own advice on that matter.

Good Luck!

I switched over to a gravity fed gun about 2 years ago and it improved my paint jobs tremendously. Just last year, I upgraded again - this time to a more expensive low CFM HVLP gun. Cut the overspray and orange peel down to almost zilch. I couldn't be happier. I do 1-3 cars a year is all, but on each job that I made a little money on, I upgraded equipment with for personal use. As I am sure you have heard though - what you do prior to painting is the most important step in the process. Your paint job will only look as good as your prep work, so be very patient and be prepared to stick with the sanding until you're there.

Most compressors give 2 readings at different air pressures, so I believe it would be more CFM at 50. What you measure at the gun though is the most important. Definately get a regulator at the gun to set up for painting. Your air cap on the gun combined with your tip size will also determine what you set the regulator at.....
