Save the Seafoam. Regular motor oil, PB, WD40 all work.

Before you drain the tank, shake it around pretty good, wait a couple hours, shake it again, maybe repeat a few times. There’s going to be quite a bit of rust dust.

I'd suppose it'd be good. I've let it soak 24 hours on some sides and over that on others. I might toss some old screws in there and shake the tar out of it though. Any tips on how to get all those flakes out the tank? Add baking soda water to rinse over and over?

Be careful with screws - I've seen that poke holes in otherwise good tanks. I prefer bearings or nuts - if they're even needed. With Rust 9/11, it already has a neutralizer, so you don't have to get too crazy with the whole baking soda thing, just rinse well and dry thoroughly, then coat with oil. A magnet does a good job of grabbing loose rust flakes that evade the rinse - although for the most part they do rinse out.

The mesh on the built-in filter that runs up into the tank is broke in some areas. Wouldn't it be fine to discard it as long as I have and inline filter? The petcock filter is still in great condition.

You can limp it a long like that, but you’ll likely be cleaning the petcock out pretty often. That filter is a big first line of defense. Measure the diameter and length on that old filter. I’ve got a few extras from petcock experiments - may have one that’s compatible I can throw in the mail.

I was thinking of getting one of those mesh reusable inline ones and maybe fabricating the outer case to work in a tank. Mines about 1cm wide and 4 and 1/8" long.

What I did was get some extra fine stainless mesh to make a 'better' in tank filter.
Also found some electrical reinforcing stuff that was already in 'tube' form to fit over cables that was easier to use plus probably filtered better than the stainless?
I think it was for 'military' applications, tin or nickel plated wire of some sort, similar but much much finer than the plastic mesh stuff sold for harnesses or on computer power supply cables.
