Default Airless Spray Gun

Has anyone tried (or used) the PPG finish system with an airless spray system?

OK, my $.02

Viscosity, atomization.

I've used this system when working with lacquer on furniture, cabinets & such. The reason I use an airless for this is as follows:

It sprays upsidedown
It has a reverseable tip (clear clogs and keep on spraying)
You can run larger meterial loads at one time to assure color consistancy.

I just don't know if it would be compatable with this material.
It sprays at 2500+PSI (HVHP) and (for lacquer) it seems to have much of the same cosistancy of a tradition compressed air system.

Maybe this is a question for PPG.

I got a response back from PPG
Quote:
PPG does not recommend airless for spaying DCC, results will be solvent pop and die back.
They went on to say they did not recommend DCC for aircraft. It also see that (like most everything else associated with aircraft) they don't recommend trying this at home:

Default Painting

From experience I can tell you that spraying your final coat is not for everyone.
You'll think, (I did too) "I build the Thing I can paint it". I tried that first on my wings using the Jet-Glo. Bad news. I had to wet sand them again. Nothing wrong with the paint or my HVLP system. I had no experience and had no idea what I was doing. Hired a guy that's doing this for a living, painting jets. First he checked the prep work and said it was first class. Than spent an hour mixing, straining and checking the viscosity of the paint. When he fired his gun, it was magic. The paint was laying perfect from the start. Than he laid on his back and in 25 minutes the bottom was painted. In 3 coats it was done.
Again: The prep work is 90% of the finish. spend your effort to do the most perfect fill and prime you can do. Bad prep work can not be masked by the most perfect paint. Than get a hired gun that works with your kind of paint.
Don't screw up years of work by trying to prove that you can do EVERYTHING.
But again, that's only my uneducated opinion
Good Luck
Buly

Loud and clear Buly. I'm thinking the entire time that I was researching this that it's a skill worth paying for. I've seen plenty of '50 foot' homebuilts and don't want to join that club.

I got a chance to see Brad Carter's Long-EZ at the Quikie Fly-In in Beatrice, NE on Rough River weekend. Beautiful piece of work! I'm inspired.

Default Airless Spray Gun

I use an HVLP gun. Not a fancy one but it works. Good for low over spray. Which leads to my question; what product makes for a better lacquer finish, the gun or the quality of the lacquer? I use PPG lacquer/satin. I have a harbor frieght gun. It has its own air regulator on it. Im just not that happy with the finish. I use two coats of sealer. I just dont get it. ANy ideas?

Bob
