primer showing through new paint
I have just completed my first paint job. I was painting black and I fixed two small dents on the hood. Well both spots felt smooth before I painted and one of them turned out GREAT. The other shows the bondo's edges??? is there something I did wrong? I used a product called halftime to fix the dent (its like bondo but sets faster) I then put 3 coats of primer on and sanded between each coat..
Any advise would be GREATLY Appreciated.
also is there a way to fix or hide this without having to strip and start over?

It sounds like the filler wasn't blended in enough. It's really one of the hardest parts of the bodywork process and can be very time consuming. It might also be that there's not enough paint for good coverage.
If you can see the outline of the body work, but can't see any color change then it's probably not blended enough. I was able to hide a few flaws before with thicker coats of paint, where you are just about to run or sag but don't.
The problem might be with the primer, some are high build types that allow for more sanding and help blend things in.
you might consider buffing and see if that helps, but usually that just makes those types of problems show up more. It really depends on how thick the paint is, if you have enough to color sand @1500~2000 grit, you might be able to hide it without cutting thru to the primer.
Color sanding is worth a try, because you really have nothing to lose except time.

Black paint also shows EVERY flaw in the body work.
With that said I doubt any color snading is going to remove any imperfections or the 'sight' of them.
Sand and Repsray.
Live with it.
Or cover it up with some vinyl stripes.

I think you may want to check the product you used as a filler. I also use the product called Half Time in my shop. However, it is a polyester putty made to go over primer surfacer(or body filler for filling pin holes) to fill minor imperfections. Poyester putty aka filler does not have the density to fill deep dents and as a result sinking occurs. This could account for the halo effect you have. We call it a bulls eye.
Hope this helps.
