Newbie need advice/help

Purchased my first board today and am experiencing some concerns much like when i bought my 1st car. This board is used from a local shop and I bought it extremely quickly without really inspecting the board prior. My issue is now that it is home I found some dings on the board along the bottom of the board and tail. I figure these are easy fixes and it would be worth using solarez to alleviate the problem. However i ran my hand over the deck and quickly found a spot that kinda pushes in which really has me spooked and I'm thinking it is delaminating! I dont know what to do and much like my 1st car i bought many years ago (Mazda mx6, a parts car lol) i fear i have to return this beautifulboard.HELP ME HOWARD!
