Auto body repair & detailing: mazda mpv fender dent, mazda mpv, paintless dent

Question
so last night i parked the van on the side of the rode, and i leaned on the front fender driver side pretty hard i guess, cuz it dented inwards the width of my bum...

a few friends have told me, including one that takes up autobody in school (tech trade school) told me that i can just reach from underneath and push it out with my hand. what do u suggest i do, and what would be the steps?

thank you.

Answer
First, rey a drain plunger and see if it pops out. If it doesn't, take it to a paintless dent repairman and see if it can be popped out. If he can't get it out, you will need to make an insurance claim and have the fender professionally repaired. Bill
