I normalized all my clips and there all hitting at -6 db peeking at 0db, I then exported the audio "One single Track" over to WavLab and normalized it to -12db brought it back to Premiere and it sounds fine... Is there any thing wrong with doing this???

Pat: I've moved your thread to our audio forum since it is much
more likely you'll get a good and quality answer there. I've also
enabled your e-mail notification for this thread so you know this
has happened etc.

I can't answer this question, so I hope other will. All the best!

What's your aim in normalizing it twice? I presume the first step was taken in Premier? If you moved the files to Wavlab in order to do other mixing, why not just perform the normalization after that.
All in all, whatever the reason, if your dynamic range is good, and you don't (or can't) notice any aliasing from the tweaking, you're probably in good shape.
In my mind, it's best to limit the number of times I change the dynamic range of the same program.

Wish you luck.
