I've seen a few sets of tanks done. Most coat only the bottom and about an inch or two up the sides, since that's where most of the abrasion occurs.

I considered it. But, being a PSI tank inspector I knew nobody would fill them. As you have to remove all coatings to do the tests. So, I decided it was a bad idea.

Straight edge to the outside of the cylinder would be impossible to verify the metal underneath was right. So, FAIL.

Same with the bottom. How can you visually inspect for corrosion and pitting of the metal if tank is coated? FAIL.

You have to be able to inspect the steel outside and inside. Paint you can tell. With a coating on it. It can be covering a lot of failure points.
