Question from an old body shop guy about guns

I am getting ready to shoot a car and I have not done any automotive painting for probably 15 years. I still have a Binks #7 as well as a gold Binks #7 clearcoat gun. I see all the recommendations are for HVLP guns. I was wondering if anyone still used a Binks and if so, what recommendations do you have regarding using it to shoot SPI universal clear?
 
I would pick up a Iwata LPH-400. those older guns really are not designed for todays materials.. You will have much better luck with something newer.
I'm not sure if the binks will break down the clear properly either.. Maybe Barry will chime in on this one.
 
The old Binks guns will work but you'll need to spray at higher pressures to atomize the clear properly and there will be quite a cloud of over-spray. These older guns were used back when lacquers and enamels were a much thinner viscosity compared to todays urethanes. I was in the collision shops when we were making the transition and with some of the old siphon feed guns it was not uncommon to spray at 50psi when shooting the thicker urethane clears-the cloud was big!
 
I get a call once in a while from an old guy like me that still has his MBC, JGA, Binks 7 and like Bob said they will work if you have the 45-55 LBS going to them and they will work fine BUT you will waste a lot of material, example say 25% efficacy rating VS 65-75%. That is a lot of material going in the air.
 
I remember calling and asking if the pressure ratings were based on either a conventional gun or HVLP gun and was told either. High volume low pressure against basically high volume high pressure. I would think using one of the 4:1 clears might work better with the old standard binks. Alot of the comments are probably from someone that never picked up a good old binks #7.I would definitely try to reduce the clear to use the binks and think the atomization would be incredible with that gun.
 
high solids were never meant to shoot through a #7 or any other era gun . reduced or not . i still own 4 #7's and several jga's .
 
Thanks for the all the feedback. Sounds like I have to decide if the cost of a quality new gun is worth it versus the cost of additional materials.
