Maybe you should read posts more clearly.
First of all I didnt give out a ludicris opinion. My original post said to use CAUTION not that it couldnt be done, you need to be careful with the products your choosing.
I have ran the PPG SV epoxy primers over USB filler with problems. I called PPG and they said themselves that epoxy primers should be used on bare metal only and other people have complained about the same issues we had. As the PPG tech also pointed out even though it may work over other fillers and primers epoxy primers are chemically designed for metal. Sealers however work better over other products.
