+1 on polishing. I polished my tops and the bowls, and painted the carb bodies in satin black. They turned out great, and only need repolishing every once in a while. If you use a high grit wet/dry sandpaper to knock down the initial roughness, then gradually polish using finer compounds, you won't be disappointed. I have a really bad picture of mine finished if you need to see an example. Let me know, and I will find it and post up.
