George L, I know I am responding to an old post but recently came across it since its in regards to my father the late Virgil Graham. To clarify his cause of death, he did not pass as a result of improper ventilation from painting a Porsche. He unfortunately at the young age of 63 passed as a result of a brain disease that he fought for over a year 1/2 believing it was a pin stroke initially. I cared for my father the entire time of his illness and was at his bedside at Hospice when he passed. I understand you may have been misinformed but please make sure you know for sure before posting for the respect of my father and his legacy. Thank you for your kind words in regards to my fathers work as a firearms engraver. He was quite talented. I an artist not in steal but in murals feels quite proud to carry on his artistic legacy, he was very proud.
