I have installed over 10 applications of Stongard. The install is not enjoyable, rather stressful IMHO. However, after 2 weeks in the sunlight almost all of the flaws remove themselves. I have only compared Xpel to Stongard and found out Xpel has less coverage area but more user friendly when applying. Both use the same thickness of film and are 3M. I still prefer Stongard, I have had great luck with their products. I use Xpel for the headlight/fog lamp protection kit. Stongard's is way too thick. Both companies offer photo's of their kits online. Take a look! Hope this helps!
