Looking for tips and advice. I'm getting better with it, but still not happy with results.

What are you trying to use it for.
Why are you unhappy with it.
What are you trying to spray, paint, stain?
Most of you questions may be able to be addressed by rereading the manual.

Do you happen to be the same person posting on DIY Chatroom?
If so you should have used a pretinted primer and thinner coats.
