Maybe this will make you feel a little better about the task ahead. I have the extra bonus of model kit enamel, vinyl wallpaper, and petrified commercial wallpaper glue on the outside! At least someone masked the badges...Oy
I picked up a Rogers kit in that condition about 10 years ago. Painted inside and out with something bulletproof.
I worked on it for 30 minutes with no progress and said 'I'm done'.
Found a furniture stripper with a big tank in the shop, dropped off the shells. When I picked them up they were bare wood, with some light staining in the grain. After they were repainted inside and rewrapped, they looked perfect. Cost? $75 for 20-12-16-snare and worth every penny.
The way I figured it, if folks have antique furniture dipped in a stripping tank and it stays together, drum shells should survive with no trouble. And they did.
