Is this B5 blue?

Keep this in mind also......

B5 is only part of it.

EB5 was first used for the 1969 model year.

GB5 was first used for the 1971 model year.

They are NOT the same color.

very true! another thing to remember, bb/cc and enamel/urethane will have totally different looks, as to the amount of cc and the sanding between.
