[DeTomaso] GT5 Air Dam - scraping damage and rock ships

[Peter Havlik]

I am in the process of having my air dam repainted after only 2,000 
km because of rock chips and damage caused by scraping on steep 
driveway approaches. I would be grateful for some advice on two 
related questions.

First, has anyone tried to apply the 3-M clear anti-rock chip coating 
to their air dam (or any other part of the car, for that matter) and, 
if so, what was the outcome? Are there any alternative products that 
anyone would recommend I look at?

Second, I would like to modify the underside of the air dam so that 
some sacrificial material starts scraping first before the brittle 
fiberglass contacts the pavement. Has anyone done this, or know of 
some other solution to the problem? I just want to hear a warning 
scrape before I damage the fiberglass.

Thanks.
