Call me stupid but I have read the POR-15 website but can't get the info I need. I have some small dents that are "rippled" shall we say. They have surface rust in them. So do I put the POR-15 on first and then Bondo to smooth it out or go in the opposite order? Next, what is the procedure for primering and painting over POR-15?

I don't know where the dents are, and that would help. First of all, don't put plastic filler over rust. It won't last.
Can you either grind or sand blast the "ripples" prior to repair to remove the rust?
Do the dents show or are they hidden in an area that the casual observer wouldn't see?
POR 15 needs to be out of the sunlight, leading me to believe the dents are hidden somewhere.
What caused the dents? Are there any other areas that need to be addressed that are related to these dents?
Maybe a little more information is in order. Fill us in on the particulars and maybe we can come up with something that will work for you.

You can call them. They are extremely helpful. The first step would be POR15 ( after going through the appropriate treatment - degrease, then metal etch using their products ). However, I'm not sure what small dents means and if POR15 is the route you should follow.

I think that this should help. The dent is one big dent in the drivers side quarter panel-right behind the tire. You know after you pull a dent out with a dent puller and it leaves an uneven surface that you need to smooth out with filler. That is the situation. I have ground the surface rust to bare metal but want to make sure that it stays away. I am thinking that my solution would be to put filler first and then POR-15 and then primer. Anyone disagree?

I disagree!! If you remove the rust, you shouldn't have any problems. If you have clean metal just use a metal Prep and then self etching primer. Then filler and primer. Metal Prep will actually remove flash rust and very light surface.

Personally, I prefer to put plastic filler on fresh ground metal only, not over any type of coating other than a degreaser. If a dent puller was used, the holes created should be welded to return the strength to the metal and to prevent the filler from going though the holes and making little "nibs" on the inside. If the metal is properly cleaned and the filler is properly finished, there is no need for POR15. Just refinish as directed by the manufacturer of the paint material you choose to use.

Hey Toby Keen,
Good point about the "nibs". We call your "nibs" Bondo Worms. Another bad thing about Bondo Worms is that they asorb moisture and cause the panel to rust between the filler and the panel.

Hey, Allen M, most manufacturers don't recomend metal tratment AND metal etch. I've been told they can actually counter-act eachother. They say one or the other, not both.
I was told this by the PPG tech line and thought I would pass on the info.

Thanks Austin!!!!
