Most here know the fibreglass around the AC discharge normally gets stained from the water running/trickling over it. I guess if the pressure is on the high side it may shoot out far enough that this is not an issue for some however on Midnight Sun this is not the case therefor each spring the resulting stain/discoloration is removed however it does require some really intense work to get the area back to new condition.

I have 3 AC outlets, the front is at the water line below the antifouling paint and the rear is under the swim platform once again just above the water line into the antifouling paint and both of these are not an issue. It is the central AC discharge located midship about a foot or so above the water line which is staining the white fibreglass.

Last year my wax guy mentioned some boaters have started to install transparent PPF (paint protection film) just around the affected area. Has anyone here done this and if so what is the outcome. Going to try it this spring after cleanup just before launch.

Are there any other solutions that you know of or have heard about?

Will post some pictures on this thread once PPF is installed unless someone can point me to a better solution.
