I haven't worked with it since they improved it. "Invested" $100 or so in a bottle then set up an airbrush
and couldn't get it to work reasonably and consistantly. When they came out with their new and improved
version a few years back, I believe they initially offed a 25% discount. I called and asked if I could return
the old product that I couldn't get to work to try the new version one word NO. So to make a long story longer
I don't use it. Instead of bringing a new customer into the fold they lost one.
I don't know I guess I'm getting cratchety in my old age, but I have started to quit dealing with
those that don't meet expatations for good service. There are a handful of vendors out there that go the extra
step to make sure everthing is right there are many more that really don't care. I know
many here have had good luck with the product so that's great. Maybe I just got a salesman
on a bad day.
As you can see many have tried to come up with different formulas but they never withstand the test
of time. So as others have said if you can make money with it I guess it's worth it.
