Pretty much. What I did is basically a skim coat. Bondo over an entire surface, then I'll knock it down with a semi-hard sanding block. If it were just the dings, I'd prolly just fill 'em individually, but there's a very slight amount of waviness to the flat (ish) areas. 2 birds and all that... waviness and dings all in one shot.Is the solution here as simple as just using body filler to cover all of the little dings?
Everything Thu said is "spot" on... pun intended. I use the 3M white acrylic putty and like Thu, normally I'd use that for a skim coat, but a few of the dings were deep enough to need the bondo. So rather than go back and forth 'tween the 2, I just did the bondo. It's kind of what past experience has told you and what tickles your fancy in the moment.
Yes, I'll use a dent puller too, but when there's waviness involved, you're just kinda pissin' in the wind with it.
