I had a paint company mix up a bit of Isuzu "804" paint for me and found some 7/32 inch black pinstriping. I took the engine cover off and scrubbed it down with Dawn dishwashing detergent to get all the oil, grease and plastic film off.
Using an airbrush, I gave the cover 6 light coats of paint. I let the paint "cure" for a week in my nice warm solarium. After the paint was for sure set, I went over the surfaces that the pinstriping was going to be laid down with isopropol alcohol. Then laid down the stripes. I then used a very fine, flat, wide artists paintbrush. and thinned down black enamel paint and did the V6 DOHC 24 Valve part.. (the hardest part!). I let everything set for a couple more days and viola!
This picture taken in October replaces the original ones that did right after I finished in March.. The finish looks as good as new and held up very well under all the heat of Summer and the engine compartment.
