'35 gas tank yuck

[Steve in Denver]

Any ideas on how to get the remaining yuck out of a gas tank? I had it hot tanked and he got most of it out.

He says the only way he can get the rest out is to cut the tank open and sand blast it.

POR 15 has a cleaner, but not sure if that will get the remaining yuck out if hot tanking it did not.

Then POR15 only comes with a quart of sealer, not sure how to get that all over the tank including the baffels. Seems like a gallon would be a better solution.
