Since "Leprechaun" is on the hard for the winter..only 85 days til launch..I have taken the teak hatchboards and side rails off to cetol them..When I took the teak inner side rails off I found a brown compond that was between the teak rail and the boat. I will have to scrape it all off before putting them back on, but do I put silicone back on? before I screw the rails back to the side of the door way?. Many Thanks .. Happy New Year to All

3M 101 preferred bedding compound here.

The process you're after is called 'bedding'. Liberally put your bedding compound of choice under or on the backside of the piece to be bedded. When you put the piece back on, you don't want to fully tighten the screws/bolts down. Just snug it up to the point you're leaving a thin layer of bedding compound underneath to prevent water intrusion. Rest gets sqooshed out.

If you have the right amount of stuff in there it will lightly extrude all around the edges. Too much and you've got to start cleaning and dressing it down. Have plenty of rags, diesel (for trimming 101) or soapy water for trimming water-based stuff.

Let it harden up for XX hours (how long depends on what you're using and what temp it is), then snug the screws down all the way. The teak (or whatever you're bedding) will now be sitting firmly in a waterproof bed.

All the above is subject to a wee bit of experience. How much stuff to use, how to apply it, how much to tighten, how to dress the edges.

You might practice with some 'minor' bits before moving onto the big stuff.

Silicone has a way of sticking to things you don't want it to - and not to things you do. It can also be a miserable product to remove.

I've always had good results with Life Caulk - tightening the attachment hardware to maybe 70%, allowing it to cure several days to even a couple weeks to form a gasket - then tighten the rest of the way.

Good luck!
