Sorry, but I'm not sure what you mean by the plastic hood body. The only plastic part on my cross Tektros' are the cylindrical cable adjusters.

If you want a really smooth/shiny finish, the Tektro's take quite a bit of work. There's pitting throughout under the paint and it took me a lot of 600 and 1000 grit to remove. Well, I didn't get it off the entire lever, but it still looks sharp.

Photo of the results soon. I still have to do the clamp.
