3M 4200 or 5200 should work just fine.
Ayuh,... 4200 is like 5200, only removable...
Which would be better?
Ayuh,... Define Better....
I like the Permatex Copper, mainly because my boat is orangy red. Most boat builders used no sealant. Any RTV fine. I would think 4200 probably better than 5200. You don't need bonding, the clamp holds it.
