Bedding chainplates - quick and dirty way
Ok, so after about a year of ownership (and a lot more time since last rebedding) one of the chainplates started to leak. Its a tiny leak to be sure, if I didn't check them weekly, I would not have noticed. Anyway, I need to rebed this one chainplate. The limitation is that I can't remove the cover plate (or whatever it is called) on deck, unless I disconnect and remove a turnbuckle - and doing anything to my rigging is not in plans right this second. So, I can lift the face plate about an inch or two, and clean whatever I can get to that way. There is almost no clearance between the chainplate and the deck on 3 out of 4 sides - I can't even slide a blade of a knife in there, so it will end up being fairly superficial bedding.
Here is the issue. The PO used silicone as a sealant (everywhere). On the one hand, evidently it worked well - considering how other chainplates are holding up. On the other - I just don't like silicon, I'd rather use polyurethane sealant. But with the limited access I am probably not going to be able to remove silicone completely. So, is it worth using silicone again (on a premise that it would stick better to any potential remnants of old silicone) or use polyurethane (probably 4200, or whatever local West Marine carries)?
This is all temporary anyway - the rig will probably come down in fall and I can do a better job rebedding all chainplates then, but I'd like to do what works for now.
