All good responses here, thank you.
Dennis, can you tell me what the difference is between the VL-3AS double Action brush you bought and the VL-3MH Double Action brush is? I see that the VL-3MH replaces the VLS-202S while the VL-3AS replaces the VLS-Set. Literature is confusing and difficult to follow.

Once again the marketing folks in their never ending quest to sell MORE STUFF have muddied the waters.
The VL model has been around for a long time (decades) with no real changes. Here are the two (2) I was able to identify:
VL-SET - Plastic handle (always) which must be removed to pre-adjust the needle, and the spigot on the bottom for mounting the cup or bottle is a plug-in friction fit.
VLS-SET - Exactly the same as VL-SET except the spigot on the bottom where the cup or bottle plugs in includes a nut to tighten the grip. Necessary? Ive never needed one.
VL-202S - Exactly the same as VL-SET except the plastic handle has been replaced with a ported aluminum handle. The ports allow access to the needle adjuster nut for pre-adjusting and also for pulling the needle back during use. Some users like to clear the orifice area during use by blowing full air and flicking the needle back and forth. Its hard to do with only the trigger. So they hold the trigger button down and forward (full air but needle is forward, then they grab the needle nut through the ports in the handle and they run it back and forth quickly a few times. My description may not make much sense until you need to do it, or you see someone do it (YouTube is your friend here).
VLS-202S - Exactly the same as VL-202S except the spigot on the bottom where the cup or bottle plugs in includes a nut to tighten the grip.
Newer model numbers:
VL-3AS - Model number change only. Exactly the same as the VL-SET.
VLS-3MH - Model number change only. Exactly the same as the VLS-202S. Im pretty sure MH stands for Metal Handle.
I hope that helps a bit.
