This I consider a rather lack lustre ( pun intended) answer to someone
trying to duplicate stock form engine shrouding paint. I have seen enough GM
engine bays that have mirror finish sheet metal or on the other extreme look like
they were painted with chalk board paint.
A good starting point for gaging the engine shroud sheen are parts not
exposed to extreme heat such as the air cleaner housing. Oh sure, years of
exposure to oil and prior cleaning can indeed polish the finish to a higher gloss
than normal...but parts that never got this attention tend to have about a 75%
gloss factor. Chassis black just doesn't cut it! It's way too dull.
Judging from the numerous attempts I have made to exact the sheen on black
shrouding the one to come closest is gloss black powder coating. Usually this
returns from the shop slightly dull in lustre...not at all like a highly
polished body finish. Of course your source might produce a better quality gloss.
Check their samples as they should be able to vary the amount of gloss.
Baked enamel was what the factory used. You will find the parts were not
primered yet simply sprayed with black over bare metal. The quick baking
process after application is what caused the paint to dull due to rapid sweating
of the solvents. The difference in powder coating is that solvents aren't
In closing I would suggest some experimentation...a good quality enamel
over bare sheet metal then quickly transferred into an oven. So far my wife
hasn't felt favourably to me using her oven for such an experiment. ;^)
