With the knowlege of the dangers of HF and it's derivatives that I gained in that period of my training I have deemed it the smartest move to just avoid the use of HF and derivatives even when the economics would suggest a compromise. The precautions available in a superbly equipped laboratory far surpass anything the casual home user can effect, so my advice would be to just keep as far from HF as possible Terry

Well said. There are a lot of other ways to achieve an etched look using abrasives that are much safer if done right. Accidents happen so plan for the worst with any product you use.
