As a doll doctor I repair anything the customer wants. If a doll has crazing I restore it. I do not use any of the products on the market, I have my own methods. BUT---My own dolls keep their crazing. Of course if it is heavy crazing on the verge of cracking, I restore it. But if it is light crazing or crazing without paint lifting, I say leave it alone! What do you think--I would like to here other opinions on this and why-I look forward to hearing from you doll lovers out there!! Louise
