Works for me — go to Autogeek,look up optimum technology- opti -guard 99$,watch opti- guard vid on Autogeek also on utube , clean car with rubbing ( after paint correction)alcohol ,apply opti-guard also called opti pro. Very easy and ssoooo simple, plus you get to know every inch of your vehicle.
But better not cause you will go on coating and protecting everything interior parts,smart phones,watches, glass, don’t say I didn’t warn ya and maybe even saved ya some coin and knowing it was done right by you. Works for me
