Is this normal? I shot a coat of primer, put the filler in the spots that needed it, sanded the filler with 80 then 300 grit untill perfectly level, then shot another coat of primer and I can see the spots where the filler is. I plan to block it all with 320 and prime for the final time. Did I do someting wrong? Will the filler be noticable through the paint? That's my main concern. Thanks FC

This is normal, the mud will pull some of the solvents out of the primer due to its porus nature. Realistically I shoot 2-3 coats of primer then wetsand. Then re-primer (a couple coats), wet sand again with 600, then paint..

Of course you don't have to "wet sand" it, you could dry sand it. I personally never wet sand primer, it just isn't that sort of product. It isn't a bad thing per se, but it isn't a good thing either.

We have always wetsanded our primer with no problems. Funny how people do things differently. Dad and Grandpa did it the same way, being that is where I learned it..

I just wanted to make clear you don't "have to" wet sand. But like I said, I never do. Now, if Dad and Grandpa did it, that doesn't make it right. Honestly, with 2K primers these days they are pretty insoluable and it really isn't that big of a deal (though it still opens the door for trouble when you sand the primer thin) but in "Dad and Grandpas" days (your dad may be as old as me, I don't know) most surfacing was done with lacquer, you CERTAINLY don't want to wet sand lacquer primer, it is a sponge.

While i agree,it may not be "right", it's not necessarily "wrong" either. And dad is about old enough to be your dad as if your age to the left is right, he's 64..

I don't wet sand any of mine, except after painting and before buffing. I don't do it for 2 reasons, first is the cost of the wet/dry paper, other is the time it takes to sand. My arms can't take all of that extra sanding. I block with the long board as much as possible, and have not seen any wet/dry paper to fit that in this area.
