If you mean the area underneath the coaming...

I had difficulty 'glassing it on my Night Heron. I had to sand it all off and redo the whole thing (not an easy thing to do, sanding between the coaming and deck).

For starters, apply an epoxy fillet to where the coaming riser meets the inside of the coaming lip. Apply another fillet to where the riser meets the deck. I let that cure, then roughed it up a bit. I didn't have roving either, so I did it that way.

I then bias-cut some 3" wide strips of glass. I wet them out on wax paper, and then used small bent brushes to press them into place underneath the coaming. It's worth going slowly. It will take a long time to clean up and will be a waste of a bunch of glass if you screw it up.

Granted, I've only done this successfully twice now. Hopefully someone with more experience responds. I am looking for better ways to do this myself.

If you do screw up, I found that a dremel tool was great for cleaning up my mistakes under the coaming. If you go that path, be very careful with the dremel tool. It abrades through the glass very quickly.

: Fairly pleased with results thus far, and prefer not to botch it at this
: point. The decks and recessed cockpit areas are glassed (6oz w/ no fill
: coats, yet). The coaming and lip have a seal coat and are ready for glass.
: The only glass experience I have is what I've done thus far on these boats
: (should have cut that damned beaded edge off the 2" tape strips prior
: to beefing up the stems! ...live and learn). I seek advise on how I might
: lay-up the glass around the coaming and lip. With all the curves and
: changes in direction, I'd like trying not to create a mess that I'd spend
: hours cleaning up.

: 1. Didn't order roving when acquiring glass, and can't seem to find it
: locally, so I'll likely try twisting some narrow strips of my 6 oz into a
: rope. Guessing it might be easier to apply having wetted it out elsewhere
: and laying in place wet?
: 2. Is it going to be easier to lay-up by using slightly overlapped separate
: pieces, to avoid potential kinks and folds, or is it best to try do it
: with one continuous piece to keep it stronger and avoid the height
: variations that might come from overlapping?
: 3. Would this be any easier to do with 4 oz material vs. the 6 oz., or would
: that even matter?

: Any advice would be greatly appreciated,
