I picked up a set of sliiightly
used valvecovers from DarkShadow so I could paint them and have them installed by Intense when I'm there in a couple weeks. Were these Frankenbonne'* by the way? After having luck with the Magic Eraser on several other surfaces, I decided to try it on the valve covers. Conclusion: Don't waste your time trying anything else before you at least try it out. The eraser breezed through the grime and I cleaned them both in about 15 minutes with only soap and water. Only a tiny bit of staining remained at the base near the bolt holes that even an eventual soak in TB cleaner couldn't touch.
So John, do these look familiar??
They're not perfect, but they were so EASY to clean. I really wish I took "before" pics...
Painted and ready to sit atop a new valvetrain in 12 days
I don't really care about that knick in the rear because you can't even see the cover anyway, but I couldn't NOT paint it
