sealed bottom bracket question

OK it has probably been weeks since my last dumb question, so I am due...

I have a 10 or so year old Tommasini frame that I have so far been unable to remove the bottom bracket from. I was stripping the frame down to clean everything. There is some surface rust on the inside of the tubes so I thought I would treat it with Frame Saver while I had it stripped down.

There is nothing wrong at this point with the bottom bracket bearings, cranks turn fine. But I fear that could change if I keep fighting to remove it.

Is a sealed BB sealed enough to leave in place and use the frame saver?

Or I guess I will resume my evening workout in the garage.

Thanks

When Ive done mine I strip it all the way down as theres a slight possibilty of getting some blowback if sprayed into a drainhole on the chainstay with the other end plugged by the installed BB. Im not familiar with recent models but I wonder if youre turning the drive side fixed cup the wrong way. If it has Italian threading the fixed cup rotates cw to unthread, opposite of most bikes w/ English threads. Dont want to assume you dont know your own bike, just a thought...

What part of the BB are you unable to remove? Is this an old style three-piece (spindle, fixed and adjustable cup, loose balls) or a cartridge unit?

It is a cartridge unit. I was finally able to get the ends unscrewed by applying more force.
