Thanks @ganjafarmer! The friend that gave me the panel routinely visits a scrap yard that has solar panels at it and they will get me more of them if I can successfully repair them. The polyurethane was about 18 dollars USD and the plastic putty knife was like 3 dollars USD and the panel was 13 dollars USD so basically minus labor and transportation I have a working 325 watt panel for 34 dollars USD which would make it (if my math is correct) a total cost of 9.5 cents a watt. :)
