We restored this piece in February of 2016 with your products. In early 2017 we had to go re-dye and top coat the piece with 3 layers of dye and 4 layers of top coat. Client is stating that it is already cracking and peeling again. How long should a restored dye last? How can we fix this and avoid future issues like this.
