Whats under your paint??

So I got in a little fender bender about a month ago. My driver quarter flare got a little crunched. I pulled off the rear interior panel and was able to push out the dents pretty well. I was pretty pleased with the results too. I was just wondering how many people have body filler under their paint and how it is holding up. I would like to fix this quater within the next few weeks with some bondo but I dont want to paint it anytime soon. The paint on the rest of the car looks like crap anyways. On most of the quater I have about 1/8" of bondo I will probably need. On one part that was harder to reach it is more like 1/4 maybe even a little more deep, right on the edge of the flare. I probably could bang it out if I needed to. So could I get some suggesstions or comments with what other people have under their paint so it will make me feel better?lol
Thanks

EDIT: The deepest part is actually only 1/5" deep
 
I'm not a body expert but I have watched some guys fix dents like that. The advice I kept getting for good lasting bondo work was to try and get the sheetmetal to look like a sheet of tin foil you crumpled and then smoothed out. Then use the bondo to fill in the wrinkles.
 
the rule of thumb if ive always been taught is try and keep body filler to a 1/4" or less. filler will crack over time if its much thicker. my pass side quarter was repaired yrs ago, and has a good bit of filler in it to smooth out the repair. it hasnt cracked at all, or given me any other problems. you basically just a skim coat to smooth it out. all those high end hot rods are uaually full of it because making body lines perfect isnt possible with metal. good luck with the repair and be prepared to get dirty.
 
most of the quarter is like you said crumpled up tin foil. There is just one part that is hard to get to from the inside that is 1/5" deep (which means I will be needing to put 1/5" of bondo to fill the 1/5" deep dent:nice: ). but I could probably bang it out from inside the wheel well a little more.

hey bryce93lx, how long has it been since the work was done? Did you do it or did a shop do it?

Would it be any better to put more or less of the hardener in the bondo?

The rule of thumb is no more than 1/4 inch so your 1/5 or whatever :rolleyes: should be fine. As for the hardner, only use the recomended amount (one inch ribbon of hardner for a golf ball size scoop of filler) any more can potentially make the filler brittle and easier to crack. Filler holds up very well when applied correctly which means banging out the dent as close to normal as you can (which you have already done), cleaning the surface with the proper chemicals (wax and grease remover), and grinding all the paint of the repair area 2-3 inches beyond the repair area. What I would recomend is to use light weight filler to rough out the dent and then switch to a metal glaze like icing or OEM metal glaze made by evercoat. After finishing the dent make sure to feather edge the paint next to the repair area and apply a self-etching primer to the metal only and a 2k primer surfacer to the whole area. (make sure that the primer used is not a laquer based spray can, theare pourous and will let moisture behind them and begin rusting). Any other questions feel free to quote or PM me

People freak about bondo in their cars, but it's only a big deal if it's there to fill huge holes. Ask any serious hotrod builder and they'll tell you that almost every badass paint job you see has bondo under it because it's just about impossible to have the metal by itself as flat and perfect as you can get bondo.

I have never used the metal glaze before. How does that work? Is it just like bondo? Whats the advantage over bondo?
Thanks for the info

It is mixed the same way but after it is sanded it is a much finer smoother product, its not ment to fill any thing over 1/8th inch and if desired it can be applied over properly preped primer or OEM finish.
 
3/16s???

And Bondo can hold up. My engine bay has a good deal of it in there and it was done by me when I was 17 and had never touched bondo before. Doesnt have a single crack in it, and has been raced, driven, and a lot of miles put on it (not to mention the abusive roads here up north).
