Thank you guys for the responses! I was in the garage for a few hours earlier today so that I will be posting some more pictures. But I bought it about two weeks ago and I live in socal so that's a yes to the heat. I believe there might have been a hit from the back side the area where the exhaust tip comes out is damaged, and I can see what looks like bondo on the other side, I will post a picture of that shortly! And I appreciate you all pointing out these things that is why I brought my problem or project here! And the area by the tool storage I thought was interesting too, it's like a wave of wrinkles. But thank you guys for your input much appreciated!!!
