I don't judge or hold it against anyone that feels differently, but when asked, not opposed to state my opinoin. I am the master of my pocketbook only (and a $hitty one at that). The 120Ml Siles is decent enough. The one brand to stay away from unequivocally (that I have personal experience with), is the Weize, total crap!
I did a beater with the siles,80 and 120, (80 on some of the plastic or areas where the 120 was just a little too much. One thing I do is put the oven on warm, stick several sheets in the oven (and replaced each as I pulled them) get it real plyable before applying it, helped a lot! Also had a blow dryer (or heat gun on low) on site where applying it, made everything go on very easy! The doors are a must, but I look at it like it's the Franks' Red Sauce of damping, I put that $hit on everything (except the steering wheel!)
