So I'm doing a pan off resto on a 69 type 1 standard and I come across bondo on the rear luggage tray. It lines the fender wells and covers to spots on the luggage try. As I go out side to look under the fenders I come across two patches in the fender wells from the outside and eachside are different. Is this normal?? bare with me as this is my first resto of a vdub.Any suggestions what these are? and do you guys have any comments on how should I go about fixing ( i.e. redue the bondo seeing its a bad job, or get a welder to go to work on it) and info would be much appreciated..??
