Please do post some information about how you made the detailing....

If you are asking about the information about the detailing of the rocket itself, some can be found in the first few posts of this thread. If you see a detail that I didn't provide info on, just ask!
If you are asking about the weathering details, I used these two steps....
Step 1: I used some "rust" color Testors paint, painted on in blotchy random areas then partially wiped off with a paper towel.
Step 2: After the rust dried, I added the black grime. I just squirted some black LiquiTex acrylic paint onto a paper plate, dipped my fingers into it and just smeared it around. Then before it died, I again used a paper towel to lightly wipe most of it off, wiping in the direction from the top of the rocket to the bottom of the rocket. This stuff dries pretty fast, so I only did small sections at a time. For extra grimey areas, I just repeated until I got the look I wanted.
It isn't hard, but it is messy. It is difficult to keep consistant from one part to the next, but that just adds to the natural random look of corrosion and grime. It is easy to overdo it if you leave the black paint on too long since acrylic dries quickly, so be careful of that. Just experiment and have fun with it. Using different layers of colors (like greens, reds, browns) and even different watered-down consistancies can add a lot of depth to your corrosion, but I didn't go that far with this one.
