Not sure if it was the filler i was using or i didnt let it cure all the way (waited 2 days) but i have had no luck with it. Any ideas as to what i may have done wrong? I have some more filling and sanding to do on my fenders and the smoother i can get them the happier ill be.

Hi, you can only wet sand a '2 pac filler' which uses a hardener in a seperate packet. Then you mix a small amount of hardener to filler ( in easy terms, a pea of hardener to a golf ball of filler usually!) putty mostly relies on just air to cure, and is best sanded dry. Hope this helps
