Hi all,
if I can get my compressor up and running I am going to spray the mini on the drive, under a tent !! I will be using a thinned rustoleum as it is what I have got already !!
What nozzle size do I need for spraying, I see there are lots, 1.2mm 1.4mm. What difference do the sizes make to the spray job??
Thanks,
Graham

Can't speak for Rustoleum but for 2 pack high build I use a 1.7mm tip and for 2 pack colour I use a 1.4mm tip.
Obviously the thicker the paint the larger the tip. I have a 2.0mm tip which I bought for spraying polyester high build and even that isn't big enough.

I was always lead to believe that the nozzle size was related to the amount of air flow your compressor could supply (to a point). And also like said above the thickness of some paint types.

Thanks fellas,
can you get guns with changeable tips or are they a fixed item on the guns??

Hi Graham
I bought a Sealy gun from http://www.justoffba...-Up-Sealey-S701 (superb service) as it was recommended in a practical classics magazine as best budget buy.
Came with a 1.8 and I bought a 1.5 set for the final (thinner) coats using celly.
The 1.5 was a kit with nozzle, air fan and I think maybe a needle as well. Spare kit was about a tenner if I recall correctly
Hope this helps

I have a Sealey gravity feed gun which has changeable tips. It was about £40 and I've been really pleased with it. My 150L 3Hp compressor will run it for almost a full cup full of paint before it kicks in.

That's the decision made then, sealy gun, and a 1.5mm nozzle too !!
You were correct Steve, £11.50 for the extra nozzle !!
Thanks fellas !!

The comressor needs to have a water trap in line with your gun last thing you want his water droplets in yor paintwork

i have a 1.8 which is my primer gun and an iwata 1.3 nozzle for my top coats and laquer.have used a 1.0 for some metallic basecoats before which turned out quite nice.

I am getting a small water trap to go on the bottom of the gun, and one on the main line feed for a permanent set up, combined with a pressure regulator. Should keep the moisture at bay !
My schultz gun turned up todat so getting closer !!
On the oiling front, I take it you don't oil a spray gun for the same reasons as water droplets from airline moisture ??

Hell no to oil!!
That would be a HUGELY bad idea!!
A 1.4 nozzle works well for most top coats and a 1.8 for primer.
Its best to have seperate guns for primer and top coat as the primer is abrasive and can damage the 'good' gun.

Good tip Neil, may get a cheap one for the primer and a better one as above for the top coats
