Sharon, I did addres most of these MDF questions to Michael, but got no response beyond I'll look into it.
Michael Skalka, at the NGA, told me to stay away from MDF, esp. because unprimed wood and wood products are not lightfast.
I've got lots of concerns about the ABS, but someone sent me a sheet and asked me to compare it to the panels I am making. So far I've only gotten a midvalue gray down. It's taking a long time to dry. I saw photos taken by Richard Bingham, showing severe warping due to cold. This was with mounting on plywood.
But Rob Howard has recently spoken highly of the ABS, so I am keeping my mind as open as possible.
Oh, RSG over gesso is a way to keep graphite from creeping through.
