Help heating Bc coils

I obviously know you’re not supposed to heat coilovers, but after using multiple cans of pb blast with zero results I don’t think there are any other options. All of my collars spin freely without any issues, but my lower mounts are stuck to the Front Dampers. So my question is where do I heat on the damper/lower mount to break them free. (I fully intend on replacing the dampers once I get them free. Can’t go any lower as it and my cars too damn to keep this trash fitment)
