Lots of good insight. I guess I've never been educated enough, or I'll be honest, interested enough to understand the differences in particular paint properties. I've always stuck with Tamiya acrylics for airbrushing because that was what I used first and its never caused me any problems...if it ain't broke, don't fix it eh? Which I think is a good foundation but a handicap at times, especially if it prevents you from trying something different.
Likewise, I think there is always something new to learn, which is why I frequent these boards. The difference is whether or not we actually apply what we learned. There are several different circumstances that effect my use of certain techniques...
First, of course, is interest. Does the final product of the technique look good to my eyes? Its like some one said, they don't do as much dry brushing because it doesn't look real. What looks good to some, doesn't look good to others...this applies to all aspects of modeling, ie weathering, preshading, dry brushing, chipping, etc.
Second is money. If a technique requires that I put out financially, to purchase new paint or equipment, generally I'll over look it. I'm a bit of a penny pincher when it comes to the hobby. Maybe not as bad as the Hammer but bad enough. Certainly enough to keep me from purchasing several different brands of paint.
Last is hesitation. Do I really want to take the risk on experimentation on this particular model or do I do what I'm most comfortable with?
So, when you first start as a modeler, your whole hobby is spent incorporating new techniques and styles and weeding out the ones that don't work with you and sticking with the ones you like. Eventually new ones will come along, that depending on your preference, you will attempt or ignore. But what is interesting is how once you get the basis for your technique down, your models will continually improve, even without the use of various other techniques. The style that you've chosen refines itself within every model you build, and each subsequent model looks better than the last.
Bill let me ask you...after 48 years of modeling, does the hobby still hold the same interest that it did when you first began? I'm sure that it does, especially if you're willing to try new things.
