Hi all.
I've posted before about this, have used the Badger "Regdab" for some time, first batch was the one with the erroneous mix, replaced with the good one. The first one caused moderate sticking as it aged, this one performs perfectly. Main benefit I find is how much better the needle slides through the bearing surface, absolutely noticeable as improved versus no lube.
This is not to say the needle to bearing fit was a real problem before, it was indeed not a severe impediment to spraying, this just makes it better if application is in a dual action airbrush, it just gives a sense that makes the trigger feel lighter and smoother in it's action.
I'm sold on it, I apply a tiny film to all threaded surfaces and the needle area that sits in the bearing. I have experienced no problems with compatibility issues, using the products I paint with. I rate it a good and useful product, I recommend it to others.
For those that can't find it, try WYN WYN search, or call Badger Company. (Badger sent me my replacement,) very friendly and helpful.
