Sara - Here is what I am doing...
I made up strips of fairly hardwood and bonded them into the lockers and bilges with 5200. Wiring will be secured with "Adel" clamps or zip ties with screw holes.
I am not sure if this is best but I wanted hangers and I didn't want to drill the wood strips in. I also bonded before paint
so that it is a wood to fiberglass
bond, not paint
to paint bond.
I did not use enough 5200 in the beginning and I need to seal the edges in several places - In hindsight it may have been better to paint the wood to protect it from moisture first.
1 - Before situation - Typical wire nest, zip tied together laying all over the place.
2 - Aft locker - Early attempt - too much gap, not enough 5200. These strips are for solar
, stern light wiring - they go low, next to the cockpit
drain and enter the bilge
floor. There is an overhead strip under the edge running aft
