You don't have to let the tank air dry. Rinse it out well with water after removing the gas and get started.
To keep from getting acid in the cap, I removed that too. You want The Works to contact the entire inside of the tank, including the top.
I don't think you need that many drywall screws. A handfull of 1/4" metal nuts worked fine, and I had some pretty heavy rust. Count the number of screws or nuts you use to be sure you get them all out. Tying the nuts in a piece of cloth makes removal easier. The acid in The Works does a very good job on rust just by itself.
You don't have to let it sit for 15 minutes between swishes, but you can.
I used acetone and in the process of getting it out of the tank spilled some on the tank. Poof! No paint. So I do not recommend acetone. If you thoroughly rinse the tank with water, no additional rinsing is needed to remove The Works. I would not use baking soda as the particles are hard to remove completely and could be a problem if they reach the carb. Put the Marvel oil in immediately after rinseing and blowing out with compressed air. Flash rust will start almost immediately, and before you can dry the tank (at least in Louisiana humidity). Does Marvel Mystery Oil displace water? I'm not familiar with it. If it doesn't, use WD-40 instead.
One of the tanks I treated had rust that developed under the "professionally" applied Kreem tank liner. So based on that limited experience, I'm not a fan of tank liners. There really is no need for liners unless there are pin holes in the tank. Keeping the tank full to minimize condensation and using Sea Foam occasionally should greatly reduce the chances of more rust forming.
I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
