[R-390] Chassis Cleaning

[Barry Williams]

Bob

I used to sandblast when I was out of highschool. For metal work, we 
called it sand texting and I've heard it's called something else now. 
Same hose pressure but small metal nozzles with finer 'sand.' It will 
leave a satin like finish pitted into the surface. Think receivers on 
lever action.

> 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.
