Removing the foam from the center of the duct was relatively easy to do, there was a fair bit of the masking tape that had to be removed from the duct.
Trial fitted theoil cooler duct with the front bar on to get before making up some mounts to fit it to the car
I used large washers to spread the load a bit as well.
Applying the flowcoat
Sanded and then applying some filler
Sanded most of the filer and flowcoat off then reapplied a thin coat of flowcoat.
