The Drum Tuning Bible also mentions a little heat to speed up the seating process. He says the alternative would be to let the drum sit for 12 hours.
I don't have a hair dryer (don't have hair either, but I digress) so used a heat gun with trepidation. I practiced a LOT on my hand and anything that resembled a thin flat surface. When I applied heat to the head I followed directly behind the hot spot with the palm of my off hand to monitor the process.
Did it make a difference? I can't say for certain, as it was the first time I used Coated Ambassadors over Clear Diplomats. From what I recall, they only needed a minor tweak in the next week or so. Will I do it again? Probably not.
