This stuff is great... I had a the full front Xpel on my WRX, and nothing got through it in 3 years of Colorado winters... That includes the 1/2" gravel they use for sand out there in the winter...
I'm in DC now, and I just got a quote for Xpel, full front, lights & everything, installed for $995...
That's too much for my blood right now, but maybe I'll piece it in over 3 months to split it up to chewable bites...
UPDATE: I had my front windows tinted at LA Tint in Woodbridge yesterday, and they have a new product, a full front kit from LLumar, installed for $775... That's looking pretty reasonable...
