redoing BHLM - how do I deal with extra silicon added first time?

Okay, I want to try to redo part of one of my headlights. It's not a big thing I need to fix, but enough that it bothers me. Thing is, when I put them back together after doing it the first time, I applied extra silicon to seal it. Can I follow the same steps in the write-up to remove the two pieces or do I need to do something special because of the silicon?

Does it get soft at the same temp? Is it going to make a huge stringy mess? Anything else I should know?

Yes, you can put them back in the oven and pull them apart, you just have to pull harder. Make sure you remove all the dead silicone and reseal though.
