Guys I'm getting ready to de-rust my tank and then seal it and want your input. Here is what I know. 1st wash with hot water and soap. Maybe include some bb's or bolts in there to break up the rust. Remove water and dry. 2nd pour in metal rescue and let sit for 8 hours minimum.. On each side if not filling it all the way to the top. 3rd. Remove and wash out then dry. 4th pour KBS gold seal coating in and slowly move around until tank is fully coated. Dump out excess if there is any. That's it... Obviously plastic wrap the gas cap in all the steps. Thoughts? Never sealed a tank before
Make sure what ever you use to seal the tank can stand up to alcohol fuels. Don't assume. If it starts to peel, inside you will have a huge mess
I used phosphoric acid (from home depot). Pour it in and let it sit like you said. If I remember correctly, it's the same as metal rescue but cheaper. I think I paid $15 for a gallon or something like that. I initially used cider vinegar and BBs to clean mine, and it worked okay, but not like the phosphoric acid. One note about the BB's, they're a pain to get out of the tank. A magnet works well, but they get stuck in all sorts of places. Also, I would rinse it with WD40 or something if you rinse it out with water so it doesn't flash rust. As for sealing, I never did seal mine. I read a ton of reviews and some seemed better than others, but none seemed trouble free. And if there were issues with any of them you were worse off than if you had a rusty tank. If you keep it full of gas when you store it, it won't rust.

great. Now I don't know if I should coat or not... Oh boy
I was just saying you don't have to coat it if you didn't want to. I didn't, but it's your choice. My thoughts were if it didn't work and I had to re-strip the tank, then so be it and I'd seal it next time. Thankfully I haven't had to do that.
The most used tank sealer from when I looked is red kote. I've heard mixed reviews about it standing up to some of the gas additives. The one that I had decided to go with if I did coat the tank, was the POR-15 tank sealer. It seemed to be better able to withstand pretty much anything when applied correctly. My main concern were horror stories of people having the liner come loose, or get eaten away, and also the sealer clogging a vent or something. It's probably just from not letting the tank dry correctly, or not following directions, but I personally, didn't want to risk it or deal with it.
One thing I did read about is people taking theirs to a radiator shop and letting them coat it. My guess is because they have supposedly done it before, or if it messes up it's on someone else.
