body filler questions

[Jonnyblaze]

have a couple of questions on body filler.. first off... my quarter panels are riddled with tiny quarter sized dings that id really like to remove and was wondering if body filler was the best way to do it. if not, what do you recommend? if so, which brand is the best?

if anyone has used this kind of stuff on dents could get pics and could you tell me whether or not its held up or if you can tell its been filled?

on another note.. ive got some hail damage(a buncha tiny little dings) on my roof and was wondering if they could be pushed out from the inside (s13 hatch)

thanks
