Glad to see that you were able to get your tank clean. Be careful using acid on aluminum as it’s very corrosive. I do use it in a controlled manner for cleaning out the oxidation in cylinder head water jackets, and a few other applications.
The Por-15 is usually used on steel tanks with holes in them. Your two-piece cast aluminum tank might be the most rugged outboard tank ever made. If it develops a leak, the leak would likely be at the seam. The fix for a leaky seam is to disassemble the tank halves and reseal it.
Save the Por for a steel tank. Just an opinion. Good luck with the TD-20!

Presently my procedure of choice for aluminum tanks
is to fill them as much as possible with 50/50 Zep
Purple Cleaner and Degreaser, and water.
It has some mild acid in it so it dissolves any corrosion
in an aluminum tank resulting from moisture over years
of them resting. I wait till its pretty much done foaming
and dump most of it out.
