Is B3 blue the same as UU1 Blue?

Even more help. I love this website.

KrazyKuda, you are so right. I was stripping everything off the somewhat faded firewall. I took off the heater blower motor. My friend Mike says, "Hey take a look at the blue that is under it and not faded. Are you sure you want to change that?" Not only was it a darker blue than I thought, it was metallic. Nice. You all confirmed what I thought.
