When I installed the torque rods I got some ca on the rods and it made the rods hard to turn so I used some 3in1 oil on them(it worked). The problem now is that the balsa at the T.E. near the torque rods soaked up some the oil and it shows as a patch of dark balsa and nothing will stick to that area not even tape. I am about start covering the wing and I need the ultracote to stick to this area. I was thinking of spraying with Lusterkote or apply thin ca maybe if these soaked in the balsa I would have a better service to stick to, HELP.
