Good point, but I I believe that to be true of silicone spray, but solid silicone adhesive applied to an area to be re-covered by bonnet tape after a re-spray should not be an issue i would have thought?
The thinking behind using silicone was to avoid banging through yet another run of tacks. As my scuttle is mild steel, not stainless it seemed sensible to avoid another source of corrosion.
Unable to hit the same holes through the thick tape was another decider.
