Yes Pain In The Ass.
When you have anything polished, you'd need to keep it polished or it'll just look a mess in time. Its not fun and very time consuming trying to keep your engine bay presentable.
I've done the entire polished engine bay and hose and bolt thing in the past and trust me. It's a lot of work to keep up appearances.
So unless you hardly drive your car and would like to open your top, flash your bits in every given opportunity like you live in Chelsea, I'd go for something which is presentable yet practical.
