Re: THE DRUM MODIFICATION THREAD.
You can take off the wrap, but be sure to get all the glue of the shells. If you want to paint them with a solid color do not sand the shells to smooth, the paint needs some grip to hold on. ( maybe 400 grit max. 600 grit)
If you good at spray painting you can try it yourself, but I would suggest you put a sort of automotive laquer over the paint to get a nice shiny look. Be sure that all those layers of paint and laquers are not too thick, otherwise it will choke the sound of the shell.
The other thing you can do is , as soon as you took off the wrap, and you like the look of the wood just sand it and put a laquer on top of the shell for a nice natural finish.
I do not know any supplier of drum hardware in the UK.
