Problem with Crank Pulley

I heard my car squeking loudy i tried putting belt dressings, wd 40, and silcone spay and alll of those things just made it go  away for a day or so then it would come back i think my crank pulley is bent because it wobbles but it looks like wobbles more than it should not just a little and i kno its not the belt because its a new belt any sugestions on what could be wrong and if it is the crank pulley and suggestions on which one i should get ?

Here's a thread that may interest you:

Crankshaft pulley wobbling and belt squeaking

The sprays that you used do more harm than good. They are good for locating the noise but they leave a residue on the belt.
I would suggest using a brake parts cleaner to clean off the belt and all the pulleys.
I have seen many pulleys wobble without crating a belt noise, but it's certainly possible for it to rub the edges of the belt and cause a squeal it it's excessive.
 

Oh yea i forgot to say it is a 2000 chevy blazer 4.3lt v6 vortec so yea lol ...
