Re: FCS fin plugs
Should be easy to find, Contact your nearest shaper and i 'll bet he'll sell you a pair. As for the fix, I only did one 3 weeks ago after landing on my fin and busting the plugs:
1/ You need to remove the old plugs and any loose foam/glass, sand down the area around the where the plugs will go.
2/ Check to see if the original fin lines drawn by the shaper are still there, they were on mine and allowed for easy alignment, if not pay attention to the alignment and mark it in pencil.
3/ Place a Fin on your replacement plugs and masking tape the bottom of the fin and the plug screw holes, this makes sure they go in aligned to each other and having the fin on helps align to the fin line.
4/ Cut two pieces of 4 oz glass about two inches x 2inches, these will be used to play in the holes with the plugs for added strength.
5/ Mix up a thick Q-cell resin mix, but not too hot as you want a longer curing time for extra strength.
6/ 3/4 fill the holes with the mix, place the glass patches over the holes, then push the plugs down into the holes, making sure you keep it aligned. you want the plugs to be the height of the rim above the board, you will sand them down later. Ensure that the mix has overflowed the holes, and flatten any glass sticking out to the board. Recheck alignment of the fin and leave overnight.
7/ The fix should be solid, so here comes the hard work, remove the fin from the plugs and use 60/80 and as you get closer 100 grit sand paper to sand down plugs and resin mix flush with the board. This can be hard work by hand due to the plug rims. If you have got access to an orbital sander use it.
8/Once flush you want masking tape a square round the whole fix and then mix up a hot coat resin mix (Just resin with hardener) and use a brush to apply the hot coat. Remove masking tape before it cures then allow to cure properly.
9/ Then use 100 grit followed by 240 wet and dry to flush making sure you feather out the edges as best as you can.
10/ To finish use either a really fine wet and dry (I use 2000) or buffer with a polishing compound for a good finish.
All done and your fix will be as strong if not stronger than the original, although it probably wont look as good! Don't be afraid and give it a go.
