Marvin:
Yes, I did overreact and I am sorry I vented at you. Do I have doubts about Marogers, yes I do. I also have doubts about alkyds and linseed oil. That is why I keep researching my materials.
I certainly need to back off of this and just paint and let the future worry about my works. If any of my paintings survive to be 100 or 200 years old then perhaps they will someday provide gainful employment for a conservator somewhere.
Beth and Sharon: Thanks for your good humor.
