I went with a 518 this time. Curious how that would work for priming drywall. Might make the 395 better for drywall priming on smaller jobs since my big old airlessco needs a new prime valve and has been sitting idle for a few years now. I don't really want to fire up the old sprayer for a basement prime job.
Dean. It's the same seller on Amazon and Ebay. :biggrin:

$59.99 is what our store charges, but he's got a reputation for over-the-top markups. He's the only BM/Miller retailer for a couple hundred miles, so he gets away with a lot of crap.
That's when going online to purchase makes sense.

Ko-inky-dink.

I'm anxious to see some test results, but still haven't received mine. Not volunteering you for this, but it'd be really cool to have some sort of measurable test..Using a sprayer with digital pressure readout:

-Video of pressure setting to spray the product with the original fine finish tips, also showing the spray pattern on cardboard or something, then switching to the new FFLP tips, showing the pressure setting and spray pattern. All in the same video with no cuts, using same sprayer, same product. I think Graco & Titan would do well to put out something like this so we can more easily quantify how much less pressure the FFLP tips spray at.
Kinda funny that Graco now has a new video showing the spray patterns of the new FFLP tips where they zoom into the pressure reading on the SmartControl as they spray, then show the difference in spray fan patterns of the new tips vs old.

They had the original video up for a while where they only showed some dudes spraying stuff, but just added the pressure reading on the pump & fan patterns to the vid. Saw it for the first time last night.

I don't know if anyone has experienced this with this tip yet but after awhile spraying, the gun will build up back pressure and hold the needle open so without warning you'll let go of the trigger but it's like you didn't. Yeah. Emergency ensues.

It's not like when you have a worn needle where it pees out when you release the trigger. It's like a ghost is holding the trigger and won't let go.

Wish I had that on video. It's funny... In hindsight.

The very first time we used a FFLP tip we had that problem. We just assumed the gun had dirt in it stopping the needle to seat. It stopped after 30 seconds or so and we haven't had that problem again. Maybe it was the tip, maybe dirt or maybe the same ghost.

I've had that happen several times over the years with various tips and guns. I don't think it has much to do with the specific tip your using.

The conclusion I came to as to the cause of the trigger sticking is incomplete triggering to start with. When your spraying something where your stopping and starting a lot, like trim or other fine finish work, there is a tendency to get lazy with triggering. You end up not depressing the trigger all the way each time you pull it.

Most airless guns will release material even if the trigger isn't pulled all the way open. After spraying on and off for a while with the needle in this mostly open but still partially closed position, paint builds up in a place it shouldn't on the needle assembly. This can lead to the needle sticking half open when the trigger is released.

This conclusion is only based on my personal experience of having had the trigger stick on me many times over the years. Since I made it a conscious effort to depress the trigger all the way every time, it hasn't happened. It's definitely a shocker when you release the trigger and paint is still coming out.

Whether my assessment is correct or not, it's hard to imagine how the specific tip size could directly effect the trigger mechanism. Perhaps I'm missing something though.

I haven't had the chance to try the FFLP tips yet. Have some on order from the local PPG, but it may take a while yet.

I haven't experienced anything like that so far, but then I haven't used the new tip much yet either. Plan on doing a bunch of doors in about two weeks so we'll see.

Also got my digital pressure guage for my 395. Will post more about that in my thread about retrofitting a gauge.

I'm sure it's possible with other tips, I've just never had it happen before. I definitely had my pressure too high for this tip. I figured out that was the problem when I removed the guard, looked right down the barrel (so to speak) and blasted my face. Luckily most of the pressure was relieved but still. A reminder of basic safety protocol.
