[Boatanchors] Chassis Cleaning

[Bob Jackson]

I've used several detergents, "mixtures", etc. with some success at cleaning really grimy chassis. Has anyone tried sand blasting? I know sand isn't always the medial used, e.g. beads, walnut shells, are popular.

What sort of media are best? What kind of gun is used? How much air pressure? How much media is expended? etc. etc. What precautions should be made, e.g. (a) for the person and (b) for the chassis, etc.?

Thanks,
