Are there any sites that teach you the basics?

I am really interested in Air Brushing, What would be the route to take here on learning how to Air Brush lures and such?

Thanks in Advance

A good place to start is to start reading through the old threads in this forum.  There's loads of info there on just about every aspect of lure making.  There are also several crankbait making and painting tutorials in the articles section at the top of the page.

Another good website is tackleunderground.com.

Thank you!
