Depending on the severity of the rust, you can put a section of chain in it, (rough links with sharp edges). wrap it in a few blankets and throw it in the dryer (no heat) for a while.

Don't forget to remove the petcock first.

its at the point that it is peeling the paint on the inside of the tank, is that too far?

There should not be any paint inside the tank. It should be bare metal.
Perhaps someone sealed the tank previously, and did not do a good job of prepping it.
POR-15 is a good sealer, but you must remove any loose debris first.
The chain should remove any loose material...it may take several attempts.
Use steel sash chain.

I would use navs idea of the chain in the tank and then rinse everything out the petcock hole. The 800 has the petcock at a low part of the tank, unlike the 1400 that has it on the center of the tunnel which makes it damn near impossible to drain the trash out of the tank.
aqfter getting it as clean as possible you can use an oil, like Marvel Mystery Oil in almost every tank to help keep it from rusting again. The MMO also keeps the whole fuel system clean. I have used MMO in the gas on my 1400's for years and even after sitting for 7 -8 months the fuel system worked flawlessly.

I always added MMO before deployments, shipping the bike, or even before long field problems.

if thats the case im betting someone tried to just spray paint over it, i only noticed it because there are silver bubbles inside the tank

Sounds like someone has previously tried a sealer without proper prep.
You might be best off finding a radiator repair shop and having them clean out the tank.
