I hate mucked up engine bay... only fingertips should get dirty unless you're doing internals and only if you open something or check oil... I like to open the hood and watch people's faces!
I agree Ben, many things that should be painted... or painted well... aren't... Heck, it gives me something to do...
next project is (1) True CF engine cover... hope to get it in about 3-4 weeks, True CF battery cover and underhood fuse panel lid pending.... also replacement of all underhood tubing with black SS wrapped on black AN fittings.... then I'll start on the wire looming. I'd like the valve covers black too!
BTW, my neighbors set up lawn chairs and come out to watch me wash the ride (I only trust 1 other person to do it...'cuz once a scratch, always a scratch... The car is coated... I never use anything beyond soap (no wax, sealant, or detailer. I do put Aerospace 303 to tires and plastic throughout the car and engine bay.
I use 3100psi PW, foam canon, water through my (spotless) deionizer, and blow-dry with my Metro Megablaster... I do not touch the car when washing or drying (No bucket technique). They think i'm crazy too! I am a bit OC, of course, so welcome to the club!
Apologies for getting so verbose... but I obviously found someone who values appearance as much as I do!
