It will cost a pretty penny, looking at that dent. Your rates shouldn't skyrocket for making a claim on a hit and run. Then again, since you waited so long to make it, you might be s-o-l.i just hope it doesnt cost too much. and i dont want to report it to my insurance cuz my rates would sky rocket you know?
Looking at the size of the dent, let the professional dent remover's fix it. There are certain diy methods of removing small dents which may not good because it could damage the paint and besides it's only good for small dents!!!!
OKay try this: (videos are included so you could see)
1, Heat the dent up with a hair dryer (gas will expand and it might just pop itself back out)..leave the door in the sun for a while (we are having a heat wave right now so keep it in direct contact with the sun - the gass expands and it might just pop out). The add CO2 (it works on dents that are fairly big) Once you finish heating the surface you spray on the CO2; voila creases go away. This doesnt damage paint. - - - dont forget to hold the CO2 can UPSIDEDOWN!!!! AND once you clean the surface you should use some polishing compound and wax to throughly clean the surface!
2. Use one of those "tv promotional" dent removers. It uses suctiong cups ont he side to anchor itself to the door and basically pulls out the dent.
Try it out and let me know GL
BTW Im in LA as well...so maybe I could help you try it out of you want! LOL! I would love to see if it will work for this dent.
