I am working up a qoute to install flex track or dura spike on ledges and sign tops of a restaurant. I'm having a tough time figuring the labor. Will be 450 linear ft of 9.5" ledge so it will take at least two rows of whatever I use. Anybody have a good idea of how much time I will really have in it? Using the product time guide claims 5 hours on the spikes but that is just install and doesn't count prep. The shock track gives no install times that I found. Any advice would be appreciated.
