Hello Everyone,



Probably by the spring I should be ready to start spraying on the polybrush, polyspray, and polytone, onto my MkIIIc. My question to the group is what kind of spray rig should I buy? About the least expensive rig is the Campbell Hausfeld HV2500 High Pressure, Low Volume unit at about $300, and it goes up steeply from there. I don't have any experience painting beyond rattle can spray paint. Besides painting the airplane, and the occasional hobby project, this is not something I will be using on a regular basis, so I don't feel that I can justify spending a ton of money on a commercial rig.



I want a decent quality finish, but am not interested in entering it into Airventure  for competition. I understand that this is a fairly subjective subject, but I would like to see what the wisdom of the group is.



I appreciate your help.

I was in the same boat as you.



I bought a 115v electric 2.5HP compressor with a 8 cu ft tank that does 6 CFM at 50psi from  HarborFreight for $189.



I also suggest buying 3 spray gun and or paint tanks  1 each for the PolyBrush, PolySpray and PolyTone.



I bought 3 of the Pint sized guns for ~$9 each and one of the Quart sized guns for larger areas ~$29.



Add some latex gloves, a good cartridge mask, quick connect fittings for the guns, a water/air filter trap and I have a good spray system that does a great job for around ~$300. 



You should get 3 quart sized guns.



You also need to practice with the complete PolyFiber system for one patch at least to get your guns adjusted right.



My first patch worked but is fairly ugly since you cant sand the PolyBrush and I applied the PolyTack without smoothing it with the iron properly. Solid but not pretty.



The next patches I have done are works of art...but it really took one time to realize what was important in the application.



PS: Watch out for the products from Harbor Freight, most of the products comes from China and my friend got a free live black 2" scorpion with his tool belt.  He didn't even need a coupon to get that bonus...

Hello Everyone,



Probably by the spring I should be ready to start spraying on the

polybrush, polyspray, and polytone, onto my MkIIIc. My question to the

group is what kind of spray rig should I buy? About the least expensive

rig is the Campbell Hausfeld HV2500 High Pressure, Low Volume unit at

about $300, and it goes up steeply from there. I don't have any

experience painting beyond rattle can spray paint. Besides painting the

airplane, and the occasional hobby project, this is not something I will

be using on a regular basis, so I don't feel that I can justify spending

a ton of money on a commercial rig.



I want a decent quality finish, but am not interested in entering it

into Airventure  for competition. I understand that this is a fairly

subjective subject, but I would like to see what the wisdom of the group

is.



I appreciate your help.

I'll throw my $.02 worth here...



Find someone who has experience as a sprayer...it is a skill like any

other that requires a little practice to get right. Most guys I know

that can do it have experience messing around with hot-rods or something

and in that experience came plenty of sanding it off and trying again.

That being said...it is a lot more work to sand down a bad spray job on

an airplane and the extra coats to try and get it right get heavy and

expensive.  I don't consider an airplane project a good place to "learn"

how to spray.



Second point here...you can build the most perfect Kolb ever built,

accurate in every way down to the nearest thousandth then put the best

fabric job ever put on an airplane as well...if you put a crappy coat of

paint on it people will always give it a slant-eye kind of look , like

"You actually fly in that thing?".  I know from whence I speak.



The money you would spend on the equipment and calling in a couple of

favors might get you a good looking paint job.  Ask around the EAA

chapters or the local ultralight strips...



Also you will have to build a good place to spray if you want a good

finish...yes I know people who have sprayed outside or in make-shift

booths and get away with it, but IMHO it is the exception not the rule.

A good spray booth with proper lighting and ventilation makes all the

difference in the world.



THAT BEING SAID...if your willing to waste a little paint and time on

some practice pieces or maybe repaint the old clunker car for a practice

job you could learn a new skill...some people pick it up quick and paint

like DaVinci !!!

Campbell Hausfeld HV2500

A friend offered the use of his, I wouldn't paint an outhouse with one. Get

a good quality siphon gun (bottom feeder) with a wide spray patern. HVLP

clones dry up while your using them. You must clean after each use even of

the same product so why clean more than one?

A small touchup gun is the only extra you might want.

   Dust and dirt will find poly brush no matter what. I think it even came

from other towns just to peev me off. It must be static. You'll feel that

when you wash your sufaces.I often wondered if grounding would help, never

tried it.

I ironed the dust flat with a teflon sheet, go ahead laugh, it worked.

I practiced on the bottom sides. They came out perfect.

Then turned them over and proceeded screw up the part that showed.
