I did my wifes hatch took about an hour the 1st day(due to fiberglass setup) I let it harden up and air out a little bit. then the 2nd day I made the face plate and carpeted the plate, late on I decided to glass it and paint it but all in all Id say somewhere in the ballpark of 20 bux for a sheet of MDF, and 15-30 bux for the glass depending if you are going to glass the tire well.
