Kinda missed it earlier, but I agree with John's post...
No paint.
It's incredibly soft after it comes out of the booth. Very easy to scratch, and if you wanted to avoid damage/marring/scuffs/scratches you'd have to wait weeks to let it harden up.
Plus, to do it right, you'd have to take every single thing out of the whole engine bay to respray it body colour. Trying to mask around stuff is a PITA and often doesn't look right when you see a seam around where you taped something.
And then since you redid the bay, you'd end up starting on things like brackets, etc.
Tons of degreaser + pressurewasher + scrubbrush to get it clean, and if you're still not happy polish the highly visible bits (Rad x-member, strut tops, top of the firewall, etc).
Looks good otherwise. Are you going to paint or polish the trans, or just leave it as-is?
