Paul, you can probably do without the Mississippi mud color, and minimal Pewter gray..... I tended not to put down any of the colors "straight", mixing them slightly before stamping on the glass....and then stamping several times till I got the blend on the blocks I thought I needed. In a few select spots where I went back an added the more vibrant colors to create some differentiation, with predominantly khaki and burnt sienna.
Yes I did 3 sections of the stock Woodland Scenics flex foam walls and 6 of the narrow splicing/joining sections from Woodland Scenics. The flexible walls are being mounted with magnets below the station level. I have a sub-control switch panel there that built on a "drawer that slides out".. and I want it hidden for photos, but accessible if I am operating in that area....
After the wash coats I can barely tell the difference between the cast hydrocal replicas and the originals from Woodland Scenics..... I am working on mounting them today and will post some photos tonight when they're in place.
John Rowlen, thanks I missed your kind words when I last posted !
