Re-glassing a deck

A board of mine had a massive delam covering the back quarter of the board. Basically the whole tail was delamed almost all the way out to the rail. I cut away the entire delamed area and let it dry for a few days. Now I'm ready to glass it again. I was planning on two 4oz patches to cover the entire area. I've feathered the glass all around it and I was going to just put the patch completely on top. But then I started wondering if I needed to let it overlap around to the bottom?

So my questions are: how many layers of glass- is two 4oz layers good? And, should the deck patch only cover the deck, or should it wrap around to the bottom even though the glass is intact (not delamed) on the rails?

Def wrap it onto the rails, probably not the bottom. Its easy on the back with the hard rails, just glass it down to the hard edge and let it run off. Sand down the glass on the rails first and you should be able to blend it perfectly well. If you don't overlap the glass it'll just crack and fall apart at the edge of the fix. 2x4oz should be fine, since you likely won't get THAT much more use out of the board. If the surface isn't flat you may want to do some filling with Q-cell. Its hard to glass a bumpy object.

Be sure to use lam resin for the glass coat, then hotcoat (sanding resin) before sanding, and be careful not to add too much resin the board will get heavy (squeeeeeege that stuff).

One more thing, use a sheet of glass thats oversize so that none of the frayed ends end up in the coat, then when the lam coat has set up you can cut away the excess.

Thats about it for my knowledge. LMK if you want to see some photos of how I did mine I'll send you a zip.

And don't use UV resin unless you've got a garage and some grow lights. Catalyzed resin may take longer to go off, but thats kinda the point. Under catylize a bit on the lam coat and you get longer working time, better bonding, and more of the excess will run off.
