The most frequent problem that we have seen year after year is film forming products that have failed. The costly removal process that must take place afterward, which affects the integrity of the logs from strippers and sanding. There is also the risk of rotting under the film forming product which is a problem not only because it is aesthetically unappealing, but it is also very costly to repair.
