Rob - You are not wasting anyone's time. I started doing my own airbrushing and clearcoating after asking for tips from Gavin and Tim. You will learn a lot from these guys - as I have 

Your first attempt looks very good - and isn't it satisfying once you take the first steps ?

thanks for the confidence boost and thanks to everyone that have helped me along the way. Hope I can be half as good as you guys one day. I do like the thought of bringing my games back to a respectable level. Will never do it as a job though.....too much fun at the pace I can do them in.
