Hey Framebuilders,

i am not sure if this is the right sub to post in but i just bought a used 1987 schwinn tempo and noticed a crack in the paint on the downtube that connects to the bottom bracket lug.

is this a crack in paint or a crack in the tube. if it is a crack in the tube, will it be an easy fix? the imgur link will provide a higher resolution photo. thanks much guys.
