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!

Thanks for the advice. Makes sense. So u actually developed a tiny leak at the seam when I 1st shook the tank before I opened the vent. I tried separating the halves after removing all the screws, but it wouldn’t budge. Didn’t want to make things worse, so I put it back together. Eventually I will want to separate the 2 halves and reseal. But I can’t figure out how without further damaging the tank. Maybe a heat gun along the seam?

Filling up the tank with piping hot water may help.

The hot water is a great idea! Thx. I was also thinking about some sort of an air or water bladder put inside to gently lift the two apart. Need to research a bit, we’ll see…
Thx

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.
Keeping with the duck tape & bailing wire solutions my
Boat House is equipped for, I have “Engineered!!!!!”an
alternative to the shake shake shake.
