Generally speaking, except for some plastics around ports, you should always avoid using silicone on boats. It is virtually impossible to remove silicone residue and nothing will stick to that residue - including silicone. 4200 is acceptable but don't use 5200 - it is permanent.

Subject: [Rhodes22-list] Tabernacle repair

Hi All,   Last year when raising the mast for the 1st time,  I had a little incident that resulted in pulling one of the tabernacle screws off the cabin top.  I'm planning on drilling out the screw hole and epoxying a hardwood plug in the cabin top and screwing the tabernacle into that so that the screw will pull out if I or some future owner ever makes a similar mistake.  My question for you all is:  should I caulk the screw holes like I'm inclined to do, and if so is silicone a good sealant, or would you recommend an adhesive sealant like 3m 4200?  Bear in mind that I want the tabernacle to pull off the cabin top in the event of a mishap.
Thanks as always,
Peter
