I used this thread for some inspiration and bought myself a cheap, small blasting cabinet for Xmas and cleaned up my manifolds off the Chevelle. I would have liked to get a larger free standing version but don't have the room to store it unfortunately. The cabinet worked great and made light work of the surface rust on the manifolds. I used medium garnet as mentioned in this thread by Jason. I think now I have the cabinet I will get some good use out of it cleaning up various parts.
