Selling my 3M kit for $350
 

I recently purchased the 3M Paint Protection Film kit that includes the half hood, fenders, whole bumper, and mirrors. I used the half hood piece but changed my bumper and fenders thereby not allowing me to utilize the other pieces. The Fenders, bumper, and mirrors are all brand new untouched in the original packaging. I will sell domestically for $350 including the squeegee and spray bottles. Certified check or money order only. Again, this is genuine 3M film. PM me if interested.

Paid $1250 for full hood, full bumper, full fenders, headlights and trunk strip.

Oh I'm fully aware, but it does become more resistant to them.

Getting full hood, fenders, bumper, lights, mirrors, rocker panels, door cups, top of rear bumper, a-pillers, and half roof in Xpel Ultimate for ~1500 including labor. Not bad for how much I'm getting down, imo.

Not from my experience.

Where in San Diego? My dad @COOL BRZ is looking for an installer.

Well, if the point of the coating is to offer easier washing and some scratch resistance, then I would believe inherently it would also resist rock chips a bit more as well.

Think about how hard a rock is vs. how hard bugs and dust are (in general). Also think about the forces involved when a rock collides with your car vs. when smaller, lighter objects (like dust particles) do. I don't have to speculate; I've owned my car before and after having it Opti-Guarded, and while Opti-Guard is a wonderful product, it does not provide protection against rock chips.

Well, in all honesty the ease of washing made it a good enough investment for me. If it prevents any scratches it's a bonus.
