[QUOTE="2manybooks, post: 9605700, member: 8267"]That is a nice piece, and a difficult problem. The paint loss may be due to inadequate adhesion in the first place, and expansion and contraction of the gourd surface in response to fluctuations in relative humidity over the years. From what I remember specifically about conservation of painted objects, the most effective approach would be to select a compatible adhesive (most likely a solution of an acrylic resin known as Paraloid B72, or a methylcellulose), and apply it in a way that allows it to run under the paint layer - not applying it on top of the paint. The formulation of the adhesive needs to be carefully selected to minimize the possibility of creating dark or shiny stains where it is applied. Anything applied on top without first securing the paint layer to the gourd runs the risk of creating a layer that will actually pull more paint off as it responds to changing conditions. And application of a wax might hinder future treatment with an adhesive. Any type of coating also risks changing the saturation and appearance of the paint and gourd surface. Sorry - I guess I mostly have cautions rather than home remedies for this sort of problem.[/QUOTE]
