I appreciate everyone's comments on the Hammerite and Sherwin Williams paints. Unfortunately I've tried them all and the colors are not close. I've also tried using the Hammerite and painting the correct color over it (both cured and wet) and it doesn't come out right. (As an aside from this, this technique does work great on wrinkle finishes though) I've talked to the local paint store which has been a Dupont distributor since the '50's and they don't have anything to replicate the finish. Induron industrial paints has a plant here that makes custom colors and I've come up blank there too. Hammerite won't give any trade secrets, so I drew a blank there too. Eventually someone will have the answer. To the person who recommended the WD-40 method, I will give it a try.
I appreciate the comment on the AC oil filter article I wrote. Peggy Millman is in the process of putting it on the Stovebolt site.
