Thanks a lot for all the comments!!! It took a while and nerves get it done.
The BD had only one ply left at the bottom with some cracks. other two plys were molded and cracked, both I removed. Filled the cracks with glue and got some sheets of wood glued in the gaps where the molded layers have been. high pressure over 3 days. Did a lot of sanding inside the shell. Same on top to close the double tom hole. BD is solid now holding tom and cymbal. I always have mics inside the BD and I can say, it sounds like the other 22“ 3ply´s I have.
For the wrap I photographed those parts of the original wrap with less or no fading. After that I did some computer graphics, finally found a guy who does the printings (not easy). Now I have sheets of 60“ x 20“.
Removed original wrap on BD and 18“, grounded and sanded them. On 12“, 13“ and 16“ I left the original wrap. Last step was covering the shells with the self adhesive new wrap.
As I saw the kit the first time I was swallowing, water and sun did their job over the years. But now I´m very happy with the result!!!
Thank you Mike for welcoming me to the forum!
