POLYCOTE ECS - Seam Loose - How to Reseal.

Question: One of the seams on my model has come loose. What have I done wrong? What should I do to reseal it?

Answer: Although we are very careful to tack all seams down and then to seal them as well, we are not perfect (although we're trying!) so the loosening of a seam may not be due to anything you are doing. Once a seam is in place properly we advise being very careful when cleaning the model to avoid wiping across the seam... wipe parallel to it. There are very few seams on VMAR models.

Generally seams are located at:

  • The trailing edge of the wing (hidden by the aileron),
  • The leading edge of the wing if swept or tapered,
  • The leading and trailing edge of the horizontal stabilizer,
  • 1 or more seams on the bottom of the fuselage,
  • Some models with shaped turtle decks may have a seam at the top of the fuselage running more or less along the spine.

If you do have a loose edge, clean any oil residue from the area and the edge and reseal with thin CA.
