Absolutely true...most folks do not invest in a decent set of crimpers.... we probably have $10,000 in crimp tools here and still dont cover all terminal styles. You sure dont get away with crimping an aircraft connector pin with a pair of AMP pliers!!!. Also, an aircraft wire or cable is properly supported and the back shells have their own strain relief. Most car builds have zero support near the crimped terminal and people typically bend the wire at the terminal....
