ok my car is a 2001 ws6 red, at some point in the last year or so something appears to have gotten on the hood, car has been in storage for over a year, there is a spot about the size of a silver dollar. it looked like something dripped or something i dont know...i took a rag and put warm water on it and placed it on top of the spot to see if it would come off...
it bubbled up like a blister

it is not peeling though.
how can i correct this or stop it from spreading? I want to bring the car out and detail it but i am now nervous as to what to do due to this paint spot on the hood.
any suggestions?
