The wrap is normally bonded on with very strong glue. If the wrap is DE-bonding the only thing to do is look at your storage is it too damp too dry too warm too cold...if you remove the wrap be careful...sometimes the glue rips the outer plywood laminate. so you get wood sticking to the wrap...if you do go on removing the wrap you need to know for sure what wood your dealing with. You need to know what ply it is... is it mahogany and hardwood or birch or maple. if the ply has got a wrap on its normally a guarantee that the wood underneath is low class top veneer..Maple is soft and will strip easy...if your putting back the covering label each cover with tailors chalk or paint you can remove easy. just a spot on the leading edge of the drum each side of where the wrap starts and ends and on the wrap too... so then its patterned to go back wood bits and all if you are putting new wrap on use a good quality wood filler to repair all shells and a good quality glue ideal a glue thats used in the manufacture of boats so two pack if required .....clean drum shell from all dust and use a a clean dust free space to glue your new wrap on... you will need wood clamps and a bead of wood to clamp in three position along the leading edge they use hoop clamps in the manufacture.... specialized tools..... personally i would not recommend removing the wrap and stain and varnishing unless you can get some nice veneer to add the the outer shell as an external covering some can be ironed onto the wood or you use strong contact adhesive.. you can then stein to your own personal color and spray ....lacquer varnish.....i hope this has helped its a big job so get people who can assist you and advise you on the project....
