I have put on new cover sills and where they sit against body underneath, I seam sealed them, to prevent water entering. I have also seam sealed them to the rear where they meet rear wheel arch. Efectively they are sealed from water ingress. However;
1) The cover sils have small holes drille in them, is this normal and ought they have bungs in? and more importantly;
2) At front of cover sill, there is a huge gap where water can enter from front arches as water is thrown up and simply sit there. The oringinals had rotted due to this problem. I am going to block this casm with Dum Dum, and then underseal to prevent water from entering sill.
Essentially the underneath of the car is water tight as it has been undersealed, and the cover sills were loaded with underseal prior to painting and fitting. However, I hate the thought of water being splashed up and getig into gaps in cover sills and just sitting. Am I right in what I am doing?
