I suspect that this is the reason.  Even the masks with dust filters AND 
chemical filters seemed to have this warning.

I really would like to have a fresh air system, but my wife thinks I already 
spend too much for tools...  Besides, I don't expect to have to do any sand 
blasting for a few more years.  Last time I did some was about 25 years ago
at my brothers - and we didn't have any masks...

I certainly hope I'll survive... 8-)   Some day (especially if I start 
another car) I'll get myself a blasting cabinet.  Once I talk my wife into 
and I get the welder, and...  8-)

Burying it is not a bad idea.  But I guarantee that there was/is no more paint 
left of the A-arms, if there ever was any.  Just a LOT of rust.  It's on my 
son's '85 El Camino, and when we bought it, I check the frame and body 
very carefully for rust.  There was hardly any.  However, the suspension 
parts, and engine brackets are heavily rusted.  I know the previous owner 
used to drive the 'El on heavily salted roads in the winter, and I guess the 
stuff just packed into the engine /suspension components.  We already 
had to replace the brake lines because or pin hole leaks from rust...

Someday when the engine gets pulled to rebuild, we'll just replace the oil 
pan, and brackets, etc. with nice shinny chrome ones...

As my wife keeps saying, "we're restoring the car part by part"...
