Well this may sound a little obscure but bare me out. I was stripping paint from a M14 Stock and found that depending on how fast you push the knife through the wet paint/stripper you get long wavy strips, short bunched up piles that look like disguarded steel from a refit or repair dumped on a Barge.
Okay, pretty sick when you are figuring out how to make Trash and Scrap for models.

Humm, thinking of the 1/700 Scale Tonnage for Faux Scrap Steel I could sell on Ebay
