sata jet vs. cambel hausfield

okay I am new here so if figure a little backtrack.. I have been trying to make cars look better and go faster since i could reach the peddles. Got into collision repair & refinishing bizz about 10 years ago... A buddy came to me with a busted up door
that he could'nt afford the $1800 bucks to fix it so he asked me to help him out..
to make a long story endless i have two guns. The good one is a sata jet nr95 hvlp siphon feed gun that I bought new 10 years or so ago the other is a brand new el cheapo walmart non hvlp gravity feed gun. I got all my body work done primerd the door
spent about 4hrs blocking primer (thinking the whole time oh boy this is going to be easy one :3dSMILE: ) Got out the old sata jet tor her down cleaned and lubed her real good. Laid down the base coat. Let it cure, shot it with clear. came out kinda rough figured "well it will lay down." three coats and an hour later it looked like my 8 year old daughter painted it for me with a bed coating gun.:eek: well 5hrs
of wet sanding later got it smooth enough to re coat. this time i I used the walmart elcheapo ( out of desperation ) and it came out flawless. What gives?? is the sata just plain worn out??

That CH gun does do a good job for the $25 it costs.. Sata is probably worn out, altho I'v never gotten good results with siphon feeds. I'v never used a 'good brand' of siphon feed.

No question SATA is a good brand, but like Matt I really have grown to like gravity feed or HVLP guns sooooooo much more than the old siphon guns. I think they are easier to move around stuff you are painting and sure do clean up easier.

Jay, Shine, and some others who do this stuff for a living may have different opinions, and those are the ones I would take to the bank.

orange peel is application not equipment. the sata would out perform the cheap gun even worn out. my guess would be you didn't get it set up right or clear was too thick.

orange peel = fluid adjustment
runs = air pressure

lubed her real good-----with what?????

you can use very small abit of lube behide the packing nut on the needle . when i painted every day i would take my gun apart and clean it in gun cleaner we back flush them and shops i worked at had gun cleaners .but i still would unbolt them and dip them from time to time reset the packing nut small parts if needed .i never did lube my needle. i have used cheap guns and nice guns i can make paint come out of any of them .like said air psi . thinner temp. and reductsion will come in to play as gun technic

a touch of Vaseline on the needle pulled back is the most i have ever done. not enough to get anywhere.
the savings from using the iwata has more than paid for its self and more. these guns would have made me a lot of money back in the 70's 80's .
but beware the cheap gun. you can create many problems with a cheap gun. yes you can get paint on it but there can be a host of problems later on. solvent pop and shrinkage being the main things.

type of air compressor plays a big part--I wouldn't want to paint with the one I'm using as a fill in while waiting on parts for my regular one and of course the shop lines will be contaminated by the time I get her fixed so maybe I can stop painting anything!!!

If the Sata was meant for finish paint then most of the problem lies in the fact that the tip is way too small. Shooting primer takes a bigger tip. The tip in the cheapo is probaly much bigger which will shoot thicker primers better.

I prefer the Sata, even given it's age and obsolete feed...Perhaps all you really need is a Sata "repair kit". I keep a few of these in my office should one of my 4 (you can never have enough quality guns) Sata's go down. Best $75.00 worth of insurance I can have in house.

Where did you find a repair kit for that old of a sata?? I am looking for a rebuild kit for it for some time and have had some trouble finding one.

They call them "Repair kits" not "rebuild kits" and your local paint supply store should be able to order them from their suppliers. if not, (DanAm Co is the sole Sata distributor in the US) you can reach them direct at satausa.com . I am sure they will be able to assist you in finding a "kit"

I used to keep a smal tube of Badger airbrush lube handy for lubing packing and the needles on my guns and it worker great, especially on my primer guns. Primers like PPg K36 and the Standox hi-builds that set up like concrete would gum them up but the lube kept everything flexible...I even coated the threads to the caps with it to keep anything from binding them up
