wait are you polishing the inside and outside?

 

yes of the upper and just the inside of the lower

 

what I mean about trading is you get someone's upper that they aren't using and polish the inside and outside. When you are ready to install it, you take off your plenum (non-modified) and give it to them in case they ever want to go stock again. Then all you have ot do is polish the inside of the lower plenum and put the polished one on your car. It would also give you an opportunity to spray the outside with clear.

 

ahhh is see. I can be a bit of a window licker sometimes.
