please explain in general terms, how it's done.
If you can show me how it looks "before and after" ...

cos, Any experienced specialist collectors soon catch where the restoration, and where not. Photos will not change anything - just visually and from all sides. Two types of building - with the help of tissue paper treated with fish glue or synthetic adhesive + ironing + ironing warm load. Then, summing up the soil restoration . Next are two options: watercolor tinting and coating or covering Lacko Lacko places and toning oil paints . And ready.
Toinen, This is not sabotage, and the restoration of normal practice. But to make the defects invisible to the " superglaza " nerestavratsionnye use methods ( like " putty ", " replacement" of the paint layer to the next layer , etc. ..)

These issues are not within the competence of the restorer . Restore or not to sell or "leave to the delight of myself" - you decide !

Painfully learns from his mistakes , because I'm asking , I hope there are people in the know - if they deem it necessary, to reason ...

Sorry to interfere with your conversation but I want to summarize . As it is not strengthened and remains craquelure craquelure ; sum restorative tinted primer and craquelure , bad taste , to duplicate the canvas is only necessary in extreme cases ( craquelure , in most cases is not) ; craquelure itself is not terrible (and therefore can not significantly influence the price of the work) is important to the current state of layers of paint and the basics.
       Craquelure may appear in several cases:
technological errors ( in the preparation of the canvas, writing the work , the coating of varnish , etc.);
mechanical stress at work;
Physical and chemical factors (fires , the impact of solvents) ;
sudden changes in temperature ;
unskilled intervention.
