Thank You Roblav,
yes the intakes are all removed, I will also repaint the manifolds that have been coated in an horrible red!!!!
I've found a few threads regarding painting the engine shrouds, but I wonder what are the chaces that new paint will last if the gelcoat is gone? I think in my case I will need to take all the gelcaot off, then add a new layer of something to smooth down the surface, and then paint it. However, the fiberglass is pretty much soaked with oil after 40 years, and I doubt the new paint/primer will stick on it.
Bottom line I need someone telling me it cannot be done so that I can buy an amber shroud

Experiences, hints, are very welcome!!!!
