How could you possibly know what I have contributed to the AMA or the hobby as a whole over the last 4 decades? That comment of yours is delusional. As far as answering other threads, if I have FIRST HAND experience with the topic I will chime in. The last one was an adhisive question, not much of a stretch that a composites tech would offer advise on an adhisive thread now is it? But hey keep lying to yourself, I see how well that has worked so far.
