Roof vent fan upgrade
Reolacing the old roof vent fan, Fantastic 4000R. Apparently the second one. Roof has two sets of holes all over the place. About half of them are where the new Maxxair installation screws need to go.
1. Old chisel to remove most of old silicone.
2. Use silicone remover and wire wheel to clean up the rest of it.
3. Drill out old screw holes and fill back up with JB Weld epoxy to drill fresh screw holes into.
4. Mount new trim with butyl tape.
