Hey guys,
I will take a shot at this, hopefully someone else with more experience will weigh in also. I recently got a senior telemaster and found the covering less than super tight. I bought an iron and heat gun, and while using just the heat gun, all the wrinkles just came right out! Its almost drum tight now I couldn't belive the difference. One of the guys I work with told me I could use a hair dryer also, but since I don't have much hair, I don't have a hair dryer.. LOL Hope this helps.
