Say there Music City,
Thanks for replying with the link to your website. You offer one of the most detailed and best step by step explanations of weathering that I have read. Really appreciate you sharing your experience and knowledge with those of us who do not yet have the "knack" for weathering.
In the past I've used acrylic artist colors for highlighting the recessed panel lines in a manner very much like that you have described. You're absolutely correct in stating that patience is required while using this process. My "109" looks real good though, so the extra work is well worth the effort.
I will be checking out the rest of your site when time permits. Thanks again and hope to hear from you soon.
