I am a newbie who does my own personal cars. Not sure of the proper speeds to use on the PC to apply the Menerza FP2 and Blackfire sealant. Also how fast are you guys moving the PC along the car? Is it a very slow back and forth movement along the car or a fairly quick movement? Thanks in advance for the help as I just want to apply the stuff the correct way and learn how fast to move the PC. I am doing my black F150 tomorrow and am a little leary about it. If it comes out good I will post a pic.
