Great tips! I will make the rounds of the paint stores before I lay
any stain on any 'good' wood. Maybe I'll get lucky.

Unfortunately, I can't track down where the cabinets were purchased or
who installed them.

To make things even worse, there is a minor variation in the existing
stain itself. Pretty much the same tint, but some is a little lighter
or darker, perhaps due to different grains in the wood.

Thanks,
Steve
