Hi,just discovered damp on my bailey senator indiana s6. It's on the underside, think it coming from wheel arch area.some sealant missing, wondering if I can do a temporary seal to stop water flow.Maybe I need to take wheel arch off and reseal when wood has dried out.Any advice much appreciated and Merry Christmas everyone.
I agree that you should dry the area completely before resealing as well as be completely sure that you have found the source of the leak, which is not always easy.
Perhaps someone else with specific experience of your model of van will add to this thread.
Seal it with polyurethane sealant/adhesive such as Sikaflex 512 & it will be a permanent repair. No need to dismantle anything. Clean area with meths & apply sealant. Works ok on mine.
