Having worked in the industry off and on for many years I have always found that polite disagreement is good as it stimulates thought and that in turn allows for the learning curve to progress much faster.
I have seen mechanics that always tossed out the statement " Well that wont work" and you ask "Why" and the answer is always " Because it just wont" HMMMMMMMMMMM what is wrong with this?? They dont know why but its not their idea so it wont work.
This forum has impressed me over the years as we see such diversity of ideas being shared with the outcome being that everyone benefits and problems get fixed. ARE YOU LISTENING GM???/????/???
Keep up the great work folks
