Paint:
The red lettering is on the '88 only. Any bright red model car/airplane paint should be sufficient. For the rest of the years the lettering is black.
Engine Cleaning:
I use major auto cleaning/detailing companies' products like Meguiars', Mothers, Blue Magic, Eagle One, Simple Green, etc. Take your time and have plenty of paper towels, soft rags, and cotton swabs on hand to do the job.
