Applying heat to PCL

[slocke0624]

Hello,

I recently bought a BLNR from an AD and was shocked to see the tech dip the screws in loctite when putting the bracelet back together after sizing. One link was stuck to where it took quite a bit of force to break and another is just stiff from too much loctite. I managed to get one loose by heating up the link with a hairdryer but the other will not budge. I'm using a quality 1.6mm screwdriver and was wondering if applying heat with a lighter would damage the PCL? I know I would be applying heat from the bottom but wasn't sure if too much heat would damage the finish. I don't want to fiddle with it much more and take a chance on stripping the screw head but hate to be defeated by such a small problem.

Thanks in advance for your help and suggestions.
