putty to fill dents/scratches on front bumper.
 

Is there any product that might do the job?
I want to be able to paint over the putty.
Im not interested in the bumper looking new, just a little better.
btw, I'd like to order a replacement for the misisng "grille?" on the R/H side.
What part should I look it under at partstrain.com?

You can probably go to Home Depot or Lowe's and get some plastic mesh to custom fab the grille insert. Otherwise I think you might just have to look for it at a junkyard or something, since I doubt anyplace has an actual part # for it.

your better off getting a new bumper... or a used one in better shape.

Yea that's true too. The first recommendation I make to everyone is to try www.car-part.com so see what you can find.

if it was just that one in the first picture id say, sure... fix it.

but that one big dent right on a body line. replace it.

what about our good friend Bondo ??

btw did you went offroading on your mazda? :P

yeah that dent is huge, it happened while I was not in the car, don't know who or when of how it happened.
The scratches happened about two weeks after I found the dent, on a wet road in an intersection, not my fault either...
The bumper is also cracked from a previous accident but those cracks are harder to detect.
replacement would be the ideal solution...I know.
For replacement, I'd need it painted, is there a way to paint the bumper by myself, or do I have to take it to a shop?

OR heat with a heat gun (or a hair dryer) and PUSH from the inside out...

Sand the scuffs on the other side and spray paint.

(Worked for me! ;))

actually your basic plastic sedan bumper can be had on ebay for cheap...like $60

that if you don't factor shipping :)
I looked at the dent again and there seems to be a crack right under it. Maybe I can slide something in and just 'pull' it out.
What kind of device shoud I use for heating, if I don't have an electric outlet (except for the car's cigarette lighter) handy?
Should I run between the house and the car with an iron? ;)

thanks for the suggestion, I think I know something that might work which would fit in there and look more or less like the original grille.
