First off you should always start off in a new forum with an introduction. you can find that section here http://www.airbrushforum.org/introductions/Hi guys, first off I am a complete newcomer to airbrushing. I have got myself a Patriot 105 after reading up a lot of reviews and taking a shine to Badger. However I have only had my brush about a month and in that time only used it a maximum of a few hours. I have noticed a few issues with it. Air leakage on the screw above my quick release, more air leakage from the cone (first screw part on the tip) and last the finish has already worn off the inside of the cup and the trench at the bottom of the cup is brassy coloured. Any advice guys. All I can add is I give the brush a good clean between colour changes using airbrush cleaner. Thanks in advance
Next after the introduction you should really start your own thread on this subject being that is may not pertain to the subject matter of this thread.
Plus it will allow you to read and better track answer given to you.
lastly and this is the most important part , We need all information , What paint are you using , What cleaning product , are you using anything like mini brushes while cleaning?
The more information you give in your own thread the better help we can offer , Also include at the very least what country you live in.
