This is the initial look that I was going for but while experimenting I found that this was too extreme and fragile, way too flakie.

Here is a strip of styrene with different methods used. The base paint is a mix of Tamiya dark brown and black, Sort of a dark umber or vandyke brown color I use under rust. Gloss and flat represent Testors acrylic clear coats and "paint" is the color to be applied over the crackle, here Tamiya flat white.





Just playing around to find what works best.

To simulate the thick rust encrusted metal I switched back and forth with the
paint and crackle twice then gave everthing a wash of Vandyke brown and black oils. When this was almost dry I applied lots of ochra umbra mixed with my rust powder.The result was a nice thick rust.


I went with the last method in the test strip and I am sumwhat happy with the result. I added some rust "weathering" but still have to do some more after the model is set in groundwork, then add some earth dust to tone everything down.











Sorry for the long post but I have to get as much in as possible. I have to use my wife's office PC to go on line, so when she's taking a break, then I have take advantage of the time I have on it.
And yes I do have a lot of time to build at the moment, I was laid of work in November,Commission models are done, so after the house work and dogs are taken care of it's time to build. I have one more month before I go back to work so I will try to get as much done as possible.
Any comments or suggestions you have are most welcome.
