I agree with the improvements! I kicked myself from day one for not cleaning and painting that radiator I guess I was so excited to get it up that I just checked out! But I agree it's the most noticeable thing that sticks out. I can't believe how fast it got dirty and not so shiny looking. There is part of the block wear the paint looks thin alt re any and the pretty silver manifolds have turned to a burnt rust color already! And it's just dirty looking overall. Im gonna clean it best i can and repaint some spots on the block. And paint that radiator! Hopefully by next year I'll have a new be cool or griffin in there instead of that factree one!
