Hello everyone, I am relatively new to modeling and would like some good advice from many of you "gurus". I got my first military model kit the other day, a Tamiya Honomag Sdkfz25. I don't have a problem building any of the models, but I would like some tips, links or anything to help paint it. I don't have any airbrushes by the way, only paint brushes. 
I need help on many things like:
•How do I clean my brush properly?
•What consistency should my paint be and how do I make it thinner/thicker?
•Any other tips on how to paint military vehicles?
•What tools should I have to paint the model properly?
I will appreciate any help. Thank you.
