Effectively sealing forward hatch
Anti-Bond works to some extent, but with 5200 it usually takes a knife edge or piano wire to physically break the bond. Then use Anti-Bond for clean up.
When re-installing, make sure you use a liberal ammount of caulk. I would avoid tightening the fitting all the way. That will force the majority of the caulk out of the joint. When the caulking shrinks (it all does) you will get a leak again. The traditional method is to tighten the fitting just enough to BEGIN to squeeze out some of the caulking. Then wait until it cures (read the caulk lable, usually 1 to 7 days) then snug up the fasteners the rest of the way. This resuls in better adhesion and more of a "gasket" affect. Then you can trim off excess with a sharp knife.
Wherever possible, you would prefer to through-bolt the fasteners, as opposed to using sheetmetal screws, but that may not be practical in your case.
