Wow, 10 pages and counting. Seems the good Doctor always garners a crowd of followers and a few hecklers. There are enough negatives in the world. Can we try to be positive?
On the original question, I don't believe a separate section is required for rusty and weathered, as this really is a style of finish. I do like the idea that Harry put forward for a reorganization and understand the limitations to a reorg from Gregg's perspective. It does seem that there are many who are willing to help.
This forum is a wonderful cross section of building styles and I am so happy to have come across it. There are wonderful builders here that are willing to share with others. While there are many styles of builds that I personally do not build, there is always something to be learned from all builders of all styles, be it automotive, truck, military, ship, plane, sci-fi or whatever. Will I ever build a lowrider? Maybe. Maybe no. If I do, will it have a killer multi-coloured layered paint job? Probably not. Is it something I'd like to be able to do at least once? Oh yeah! It is a technique that requires practice and techniques. While I do try to do or learn something new with each build or improve on techniques or what I see as previous failures, I do enjoy the hobby and it's many facets. To think that for the most part it is all starts with plastic, glue and paint and becomes a piece of art no matter what the subject or finish is just flat-out awesome, whether it is a car, plane or spaceship we can all learn something if we allow ourselves to do so. Shiny or rusty, new or old, it's all the same materials.
Thanks. Good night.
