My friend brought this board to me where one of the fcs rear sidebite fin plugs had been pushed in, then pulled out. Upon inspecting further I found that the original installer (won’t mention the board brand ) Had drilled the holes for the plugs oblong, so there is a solid 1/4" bead of resin around these plugs. SO this plug that I’m trying to put back in is got a healthy halo of resin around it, and it sits low in the hole from being pushed in. Also, the glass on the bottom around the plug is soft, so it will have to be cut away.
So here is what I had in mind as far as making a solid water tight repair, and reusing the fcs plug.
1.) Mix 3 small cups of resin, one has milled fibers, one has cabosil and finally one that is just regular resin with some surfacing agent.
2.) Cut a square of fiberglass to fit in the hole around the plug and lap over onto the bottom of the board. and Cut a few more smaller strips to lay over and around the fcs plug on the bottom off the board.
3.)So I’m thinking using the cabosil mix for the foundation of the bottom of the pushed in hole, then pour some milled fiberglass resin in, adding the square, push the plug in tight, check the depth of where it sits and make any minor adjustments. Then fill in more around the plug with the milled fiberglass mix. Do any surface lows on bottom around plug with cabosil mix. Brush down excess glass from the square. Lay down smaller strips to secure everything and brush on the regular resin mixture. Then come back after its cured and sand off excess. At the very most, hit anything missed, but should be able to get it all in one shot.
This board is not a real beauty or anything, just trying to get it water tight with as little investment for him as possible so he can get back in the water. Its a beginner board.
Input, feedback appreciated, I’ve never messed with FCS system at all. Thanks!
