This is my first FCS plug repair, and I am very interested in criticism. I found this Bullitin Board after the repair was done, and I have searched the archives here and I wanted some additional information if you could help!
You can see how large the hole was after I removed the plug, because the material holding the plug in is clear resin. I filled half this hole (through to the deck glass) with a filler mix (q-cell). Then once that had gelled, I attached the new plug to a fin and inserted it into the surviving FCS plug, and filled the crevasse with sanding resin. I then sanded the whole thing down, including a 1.5" circle of the old layer of glass down to the cloth, and taped over the new plugs holes. Then I Glassed over the whole thing with 4oz cloth. As you can see, I dont gloss coat and polish. One thing to keep in mind is that I angled the board in the sunlight to accentuate the weave. I can run my hand along the repair blindfolded and feel no contours, only the roughness of the weave along the edges.
I wanted it fixed ASAP, and I had heard that q-cell weakens the resin while filling it. So I just used the resin to surround the plug. Was this a mistake?
BONUS: Should I begin the practice of polishing? As you can see there is some weave of the new cloth showing, and I sometimes think that I should begin glossing over this.
