I've just completed the Rust Blast surface prep of my bike's tank. The Rust Blast was in the tank for 50 mins, and the tank was rolled every few minutes to allow full coverage. After draining and flushing, I noted that all the 'rust' colored stuff was gone, but there is quite a bit of very hard black looking rust remaining. Will the tank sealer adhere to this stuff, or should I look at giving it another Rust Blast treatment?

I've just checked it again, and now there's flash rust all through the tank. What should I do?
-
If you have some RustBlast left, I would soak those areas again. Rinse thoroughly,
- let dry completely
-
I will get some more RustBlast and repeat.
The instructions with the kit say do not leave the RustBlast in the tank for than 1 hour. Given the heavy deposits, would it be safe to leave it for longer than 1 hour?

Yes. That would be fine. And you can also use the RustBlast again.
I grabbed this section from our directions for you:
Important: Do not allow RustBlast to dry on surface. This avoids too heavy of a zinc phosphate buildup which can adversely affect the sealing process. After sufficient wet contact, drain & capture RustBlast in a bucket/container. Repeat process as needed. Once thoroughly etched, drain and rinse tank thoroughly several times with water. (NOTE: It is not necessary to remove every last bit of rust before sealing. Gold Standard Tank Sealer is very capable of bonding to & permanently sealing any remaining rust or corrosion.)
