    I have a support that has been stored in my closet for at least ten years. It is Belgian Linen mounted on Mahogany board with Rabbit Skin Glue. It appears to have vertical shiny lines which I would imagine to have something to do with the RSG. The surface does have a slick, slightly greasy feel. 

    I began to paint on the panel with a wash of Warm Sepia Extra and Gamsol to do the line drawing as I have done for decades. The head and hair portion are two days old, plenty of time to dry to the touch. When I painted on it the next day the end of my Mahlstick touched a portion that I had done the previous day and took off some paint from the surface of the Warp of the Linen. The next day I took some paint without Gamsol and began to model the darks on the figure. This morning as the video shows I can lightly rub some of the paint away which has never happened before. 

    Needless to say I am concerned. Before even attempting to continue I am writing to you, and am shortly on my way to the person that has been making my supports since 1986 so we may possibly see what the problem might be. 

    Any insight would be greatly appreciated. I’d like to continue on with this support if possible. My paintings have very little paint on the surface, no medium, and usually about three or four passes.

    I do not really think that I can comment on this with the available info. Please let us know what you find out from your substrate preparer.

    ​Brian, Is there any information that I could provide you with that might help?

    ​You mention a greasy feel... What is the priming?

    ​Matthew, it is oil. Most likely Lead White. It was done about 20 years ago. The person that built the support has never seen anything like it and we (3 of us) could not figure out anything that was logical. The RSG had been put on the back side so nothing penetrated from the back. It is now having new linen by Claessens put on.

    ​From the last photo the surface looks quite glossy.  A small amount of stand oil is sometimes added to oil primer to aid in leveling out.  In this instance I wonder if too much was added.  Thus reducing not only tooth, but also with the very thorough aging of the paint surface, one imagines it sealing the surface from any interlinking of the newly applied paint.

    Mark.
