My 40 years of autobody experience is not needed. ODT has plenty of experts that know nothing.
In 92 I bought a new Silverado and it received similar damage. Almost all of mine had to be replaced, within the top and a few other body panels. It made me physically sick seeing it after the tornado hit. At least for you bought yours that way, black paint shows every imperfections.
If Gunanddoglover hasn't chimed in yet, he could point out a good direction to take on types of repair to go with.
