You're right! I totally forgot about boiling water. Duh! I couldn't remember if there was another method but that was it.Be careful using a heat gun on fiberglass. I have had parts blister, maybe from trapped air bubbles? I have had better success dipping in boiling water. You can just heat the affected area this way without either heating the whole helmet or focusing too much heat in one area.
