I know this might look boring, but for some folks out there, they might not know the specific procedure of how a tank gets painted. Before a tank gets erected, many times the steel parts and pieces of the tank get blasted in the shop and then get a prime coat applied. That's what we're looking at in this picture. What you see here is a prime coat of Induron PE-70 that has been applied to the legs of the tank in the shop. This prime coat of PE-70 has been applied to about 4 to 6 Mils DFT (DFT=Dry Film Thickness).
Notice the shop primer does not cover all the way to the end, and is not on the weld seams/joints. This is so the tank can be welded together in the field without the paint interfering with the integrity of the future weld procedures. These weld seam/joint areas will be touched-up in the field by the field painting contractor, after the tank has been fully erected.
Also, notice the color of the Induron PE-70 Primer is tan. The respective color of each coat of paint should always be a shade or two different than the one before or after.
