I think that is wild speculation. There are two things rust needs, moisture and oxygen, buried under epoxy primer it has neither. That little bit of rust obviously isn't a good thing to leave, but it isn't the end of the world sure to fail conditions either.

Buried under that epoxy primer it will sit there just like it is until it is introduced to moisture and oxygen thru a chip or something. Until the wheels will look purty.

If that was the case Brian then whats the difference in using por15 or epoxy they'll both seal out moisture and going one step further when you buy a new car its epoxied on both sides so it should never rust, right? in this case sandblasting ,ospho,then epoxy is a combination that cant be beat, remove any one of these and they'll most likly start rusting out within the year ,around here anyways.
Epoxy is the best way to seal and keep out the rust but if the rust is already there even in the smallest amounts,all bets are off....

rust

all rust will need to be removed yes. sandblating will do this. and yes must be 100% dry, before sealing or any type of topcoating. Otherwise, any trapped moisture can start the rust process. Bottom line, no rust, and dry.

I never said it wouldn't be better if all the rust was gone or ospho used before epoxy. What I said was it isn't going to be falling off as he goes down the road because there is a tiny bit of rust left in the bottom of those pits.

They are only wheels

The 1st time it rolls down the road it will start getting sand blasted all over again. but this time blasting the finish. I had a customer with a Chevy truck and every spring he came in and had the wheels done all over again in fleet white paint. It was a daily runner truck, Dont lose any sleep over painted wheels

Ever thought of just buying new rims?

How much are you into those rims now? With the product you bought, your time, and the 'finished' product, maybe it would have be cheaper to get new. However, if you appreciate the experience of the job, that's a different story. I would suggest sandblasting them with a medium git and starting over.

This time I would have them mounted outside the garage, pre-warm them in the sun. Make sure your product that your using is also warm too. Spray on light coats first, allow them to sun dry in between coats and make the last coat a bit heavier.

Rattle can sandable primer and doing them one at a time many also net you a better end product.
