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"...
96 Ford Ranger 4x4 - My wife drives it
94 Miata R Package - My daily driver
93 Honda Accord - My daughter's car
85 El Camino - My son's car - I'll never buy another "old" car again...
72 Lotus Elan Sprint - I bought this one when it wasn't old...
67 Camaro - Don't have this one yet, but it's my daughter's dream car...
Maybe I'll have to buy one more old car...
