re-bedding shrouds

[Ceawolf]

I have a 'new to me' capri 18 with a little rust at the shroud plates inside and out. A fellow sailor recommended a product called FSR to clean the rust off and he also said we should unscrew the plates clean the rust off and use bedding compound to seal the deck under them - so do we have to loosen both sides at once? is equal tension by guesstimate safe enough? anyone have experience with this? Thanks in advance for your thoughtfulness -

Good question. Pretty much everyone on this forum has experience with chainplates. You can do one at a time. If you are doing it with the mast up you'll want to run your main halyard over to the side of the deck where you have released the turnbuckle and chainplate to keep the mast from bending or falling. Attach the halyard and take tension before you release anything.

You can readjust the rigging once you get both sides completed. Google tuning your rigging or ask the question here again once you've completed the reinstall of your chain-plates. Use a sealant/adhesive that stays flexible. Boatlife polysulfide is pretty good. Maybe 3M 4200 would be ok.
