I've noticed with my last two clock repairs that the main spring tends to bind or stick after reassembly. One was a closed barrel 400-Day Clock the other open from a Sessions movement. I used RBG Enterprises Lube Lite that purchased from Ronell Clock Supplies. I'm wondering if this is normal with new or newly cleaned and lubricated main springs or are there better less tacky main spring lubricants? The clocks seemed to run fine after letting the movement run without the escapement.
