How do I open and close the bottle?

Dear customer, thank you for your question, you only need to forcefully pull the white bottle cap to open the bottle, the white bottle cap has no screws, so turning it to open is ineffective.

Good for sticking the otter ring/pulley back onto harmonic balancer?

I believe you meant the outer ring or pulley ring that the serpentine belt rides on. It's not typically used for applications where torque or radial forces are applied. It's used most often for cylinder sleeve installation or other sleeve type applications or when one needs a thread lock that is beyond red level thread lock. I've seen repairs for the outer ring on harmonic balancers being made with epoxy like binary adhesion compounds, i.e. JB Weld

What is required to disassemble the parts? Is heat required?

Dear customer, thanks for the question, When dismantling, it can cooperate with mechanical auxiliary equipment and heat the components to 200~300°C (392~572°F), or it can be dismantled after soaking with special scavenger for a long time

Can this be used inside an automatic transmission on pressed in bushings?

Will definitely help retain them in place. Get the primer to speed up the cure time.
