[Shop-talk] Compressed Air Lines, RapidAir

[John Mitchell]

If you plan on doing any car painting with the air system, I would 
recommend copper for it's ability to pull the heat and moisture out of 
the air.  I don't know if this hose is dramatically different than using 
plastic piping, but I've heard of catastrophic failures where shards 
were thrown into the work area.  Just my 2 cents   John Mitchell
