Just curious if any of you think it would be advantageous to polish the inside of the jet housing and your impeller. The jet housing is very rough and the edges of the fins are not sharpened. The impeller would be easy to polish as I have mine out already. It fixed up nicely BTW. But now after looking at the housing, I can see some restrictions in it that I think would benefit from some smoothing and sharpenening. What do you think??
