Sorry I do not know the 3M system you mention but I do consider myself part of the "
younger more knowledgeable guys"
I am a big fan of the Bic lighter and the radiant heat it gives off. I use it in conjunction with my Mini Raytek to monitor windshield temp. as it rises. Depending on how you move the flame and or how far you hold the lighter away, you can have the desired rate the temp. will rise. I like to get it between 70-90 deg. IMHO a Bic lighter and a temp sensor shouold be in everyones tool box. Supper easy technique and very effective.
Some may disagree here, but if you have your injector tip pressure set right, you can heat during vaccum or pressure cycles. I do it all the time. Did I just jinx myself?
Maybe the heat thing should be in a different thread.
