Zaktek, LEX and Tirexam

Has anyone purchased these products (clearcoat, interior scotchguard and road hazard tire protection) when buying a car and then felt like you just bent over and grabbed your ankles? I'm trying to mentally justify the additional $29 to my monthly car payment for these items. I didn't realize that the clearcoat has to be reapplied every 6 months at the originating dealership which is an hour away from where I live. I know I'll never drive up there. I just leased my car a week ago and am now feeling regrets. It's not so much the $29/month as it is the feeling that I got shafted.

Is there anyone that has purchased these services and NOT regretted doing so?
