First off I want to say that I just found this WIP and I am absolutely amazed at your work. Your method for achieving the TPS scheme produces the most realistic results I've seen so far. The Salt Weathering and Black Basing techniques are good methods but in my opinion, not as good as liquid masking. I also appreciate the videos you've shared that show your techniques in action. I'll definitely be trying them soon I but know that I won't be able to achieve your results any time soon, or ever!
I'm looking forward to the completed model and hopefully an article.
