— So this is a brush. There was a car that needed to be cleaned. It was starting to rust, and you have to clean it with a metal brush. But you can't get everywhere with this type of brush. It wasn't convenient, it really wasn't. But I had to get in everywhere (...) So I had to make a kind of shaving brush. I got a brush from some guys at the foundry – they weren't using it. It was circular, and I took off the binding and tied the bristles of the brush up like a shaving brush. It turned out to be an excellent metal brush. It's narrow and very convenient to use to get in there where there's rust... and in other places where a regular metal brush can't fit. You need a small one for some spots. With this brush you can get in there, once, twice, give it a good scrub, and you're done. Then I applied some rust proofer, and then it was ready to paint.
