I rubbed in two coats of Watco's teak oil on my drums. You need complete dissasembly but this isn't rocket science. It makes them look MUCH better as it has a slight amber color tone and brings out the grain. You dont need to sand anything and it's very hard to screw up. It brightened the sound somewhat but cant measure this. Just need the oil and a rag. Again not rocket science but it may devalue the drums in someones eyes but not mine.
I wanted the interior sealed and now it's sealed.
