Ahoy Swaylockians,
When I install a Single fin box (10.5 FU) I always laminate a patch or two of fiberglass over the entire box after I grind the box down flush with the bottom and sand the hotcoat. I do this by taping over the slot in the box,Laminate patches, then I cut the outline of the tape with a razor, hotcoat, then peel out the tape. Then I sand that bit of hotcaot, retape the slot, then gloss. This method has worked well for me but I have heard rumor that you can laminate patches right over the finbox without taping off the slot. Then after gloss you can use a small flush trim bit to route out the fiberglass. So is it true that when laminating patches over the finbox that resin will not drip into the finslot? I don't see how this can be but I have heard that it won't drip in as long as you don't use too much resin when laminating. I am just a little scared to try this because I don't want to ruin a finbox install and possibly have to re-install a finbox if I blow it. I probably should just go for it but I am a chicken I guess. If any of you could confirm this technique for me that would be amazing. Thanks again Swaylocks and may there be waves wherever you are!
