Have most of you cleaned up your firewalls?

Mine has all the original holes, and a few extra. Original paint and some extra. It started to collect dirt the day it was made and I have nothing against that, so on with the collecting. That's where I have my firing order written with a sharpie. Also where I keep my fingerprint's perfectly preserved just in case I become a missing person. It will get the extra holes filled and cleaned/painted when my mockup is all done. Till then it's protecting the metal under it all. O and I almost forgot. The wipers are under the dash, and the blower motor only stick out a little, along with heater hoses.
