SP/SSW SD7 Help

I then used putty and filled in the gaps on the side.....

 

And the back....

 

I then shaped the dried putty with a hobby knife, painted and weathered.

 

No photos of the process, just of the tool! I dip this into the chalk, and start rubbing from the top down. On the SD7 I rubbed the top all around the exhaust stacks with black. Then I used black, dirt, rust and made different passes from the top to the walkway. There really is no wrong way to weather. Things get dirty! The trucks were done the same way. I removed the plastic side frames, then used black, rust, and dirt again, rubbing it into the different crevises. Then dullcoated. I'll get pictures the next time I do a weathering job.

 

Here's a link to all the work done......
