I just made a picture frame from Philippine mahogany and I stained it with a red mahogany stain because it was so light in the raw wood state.  Now 5 days later, the stain is still not dry – I can rub it with my finger and get stain on my finger – it also feels tacky.  I’m going to try to seal it with polyurethane as a finish, but I’m not sure it will work.  Any advice?  I don’t think I will work with that wood again.
