Greetings! After much restoration of the teak, I am finally able to re-bed my boats caprail. this is what it looked like before removal:
I am planning on using Life Calk to bed the caprail. My question is about how to apply the caulking itself to the rail. Below is a real crappy diagram of a section of the rail. The left is the blank rail, the black circles represent the screw holes. The middle section represents my first idea on how to apply the caulking, a bead along the edges and around the screw holes. The third is the alternative method, of applying caulking and spreading around the entire bottom surface of the rail.
Which of these is the correct method for sealing it up? I figure the last one is the most thorough, but it probably wastes a lot of caulk and I worry that it will ooze into places like the chainplate holes that I need wide open and unobstructed.
My second question is in regards to the screws themselves. They are sunk into holes that will be plugged up with bungs (see first photo). Is it wise to apply some caulking to the underside of the screws to seal up each hole? Or is that overkill...or a bad thing to do for whatever reason? My other crappy diagram below, the first is bare without caulking on the screw itself, the second shows my idea of the caulking under the screw head.
Any guidance would be appreciated
P.S. I don't intend this discussion to debate the choice of bedding compound, that has been discussed plenty in other threads. So please just help me out with my questions without saying something like "You really should use X to bed it"
