MP Turquoise on the 440....

PPG 3116 enamel without catalyst on the low deck/raw aluminum heads

PPG Shopline 3116 Single stage catalyzed Urethane on the Hemi

3116 was recommended by Steve Dulcich circa 2001, later on I found out it was the
exact formula MP used on crate engines for many years.

TBH I preferred the coverage of the old enamel the PPG store doesn't want to sell anymore, and
will give the Hemi one more coat + will probably clear coat it with some kind of high solids
clear.

When I run out of 3116 I'm probably going to generic/industrial Omaha Orange as used on various municipal
truck applications and so on as it's more easily obtained in enamel and will use a catalyst.....

They all have their ups and downs, it seems I can more easily get a thin, slightly dull OE looking finish with
spray cans than I can with a gun and higher quality paint, but the higher quality paint lasts longer and looks
much better.
