This is when things got serious when I decided to sand the cab down to bare metal to prep for paint I found bondo over holes and 1 inch deep bondo in dents!
this is when I decided to buy a stud dent puller and I'll never look back if you not got one they are amazing. Mine is just the diy £ 179 version and trips out on thermal over load if you work it too fast but is more than enough for what I need
