I'm really afraid of breaking them off so I'm wondering if either of these approaches is better. I'm leaning towards #1. I've been squirting them with AeroKroil several times over the last 24 hrs in preparation of the extraction.

I have found over the years that a 50/50 mix of Acetone and ATF (automatic transmission fluid) works better then any over the counter products. Use it the same way you use AeroKroil just shake hell out of it each time before you apply it.
