Welcome to the Brethren!
Sorry, I can't help you - pictures would help to judge if the amount of rub used was the problem. I haven't used that rub before, so I don't know if doing so early would cause the over-saltiness.
Next time, please take some pix - because the rule 'round here is, "No pictures...didn't happen."
I'm sure others will chime in with more knowledgeable advice...

And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified. [Acts 20:32 KJV]
