: Questions on using an older spray gun and newer paint?? First timer!
cody Oct 20th, 03, 9:55 PM Hi, i know absoulutely nothing about using "real" paint. My car is 2000 Dupont bright blue that is used on corvettes. I have the firewall down to metal along with the undercarriage of the car. I plan on painting the firewall,cowl, and innerfenders the same color as the car using the Dupont paint. I have a husky oil motor 26 gallon xompressor which i believe has about 6.0 scfm. My dad says that he had a really good gun, but it is a older gun, he said it was a Bink 7.(or something like that) he said it was a really good gun back in the day. My question is; Will this gun work with the newer paint? also is the compressor good enough(i don't really have access to a different one)? and I read the post by MARTINSR, but i am wondering if the techniqes and rules are different when using these paints/guns? any kind on info is great. I will probably be posting more about using bondo, wetsanding, painting, and primering! but that is for later! thanks again!

Yeah, the Binks #7 was top of the line..about 35 yrs ago! :eek:
They have a Huge fluid tip which was great for heavy bodied enamel paints, but not so good with base coats.
You can probably get by with it for what you're doing, but it's not something you'd want to use for a complete base/clear job.
You're compressor is questionable at best, but again for what you're doing, (small pieces) you can get by with it. The problem you'll run into is keeping a constant pressure, and running out of air.
If you're spraying base coat, you'll want to dial down the fluid needle, and crank up the air pressure a bit. I'd suggest you practice on an old hood or something first to get the hang of it, and get the gun dialed in as best you can.
vettefella Oct 21st, 03, 9:34 AM As already stated, the compressor is below desireable minimums, but still usable.
The Binks #7 gun was considered by some as the top-of-the-line gun for many years by many painters. Frankly I am not/was not one of them even though I have one right now. The gun did do a good job of spraying heavy enamels, but it was also used on millions upon millions of lacquer jobs for spot repairs as well as overalls. Since lacquer has a higher viscosity than base coats, the thinness isn't a big factor; however, it sure is easy to make a run.
The biggest single factor against using "old" paint guns on today's paints, especially Dupont or any highend paint, is the low transfer efficiency. At today's prices, using nearly twice as much paint material with the "old" gun versus an HVLP gun can make quite a difference. But if you were to step up to HVLP, then your compressor really becomes below minimums.
Sometimes, you do what you need/want to do with what you have available. Back in the 70s when I was in Japan, I used a one HP Craftsman compressor with a pressure/bleeder type paint gun to do overall paint jobs on cars as well as custom work on motorcycles. Where there's a will, there is a way even if it's not the best way.
Get a good gravity gun. With the older guns, most of what you're spraying goes in the air and not on the car.

Can anyone help me find out what the procedure will be setting up the gun, is it different than the HVLP guns like in MARTINSR's post? thanks again!
