The description of what your problem is is somewhat short, but I'll
just to hint on some possibility, only regarding oil paint layers
and more particularly on fabric support: If you can get your object
with the paint layer into a humidity chamber, professional high tech
or self-built, and get the humidity up to +/- 80% (no less than 75%
and for shrink reasons no more than 85% Rh--that limit leaves a
little lee-way) your oil paint layer will be soft and elastic,
treatable--depending also the support. I don't advise and take no
responsibility for any further steps, like using a suction table,
hot spatulas or else; lots of possibilities to achieve in a
controlled way the required flattening. The basis of this approach
are research results, referred to in Marion F. Mecklenburg's since
ever unpublished but widely known paper: "Some aspects of the
mechanical behaviour of fabric supported paintings" Research report
supported by a grant from the National Museums act--short
"Mecklenburg 1982".
