Enough heat yeah. If you heat the bolt then immediately go at taking the bolt out you won't need to heat it so much. It takes time for the heat to make its way all the way out the damper to the rubber bits, and by that time it should already have dissipated enough heat so it wouldn't be an issue. I will admit though that I have not yet attempted to re-use that damper, but theres no visible melting that I recall.
