It's a very broad question you have there, you know. A lot has been covered at least once somewhere in those forums. If you are able to define your questions a little bit more, you'd get a better chance of having a number of suggestions for you to try. For instance, getting rid of seams. You asked about that in your KC-135 topic, but it can apply to any model really, so it would have been wiser to put that question in 'techniques' for instance, rather than under KC-135. Let's face it, if one is not interested in your KC-135, then you are missing out on someone's tips on how to remove seams! Hope this helps!
