So i am done with fiberglassing except for hot coats and gloss coats. But i noticed, where the deck overlaps the bottom of the board, there is a small ridge bump that goes all the way around the board. I dont know what to do, how to make it go away, or anything. I searched around and have seen that most people just sand that down witha sandig block or something. I am doing my best but the bump is still very visible and hard to remove
I dont even know where to begin. Help a noob out.

Here’s a video I made of bammbamm a few years ago. Watch it and learn. He grinds laps at the end.

Nice video, interesting to see how a pro works, a lot different from me, LOL!
(I sand the laps by hand, with a sanding block.)
Thanks for posting that.
Make sure you use fresh sand paper of a sharp surform, and the lamination is kicked hard, not green and rubbery. You want to cut the resin and glass, not mash it down.
…hello fellas, I think he s referring to that kind of “channel” between the deck lap to the bottom and the bottom itself.
.The only time that shows is when you leave the board in the hot coat and check the board with shadows/lights contrast.
If the finish will be a gloss coat or a double hot coat, that thing will hide.
If you plan on leave only the hot coat, I suggest to apply a coat on top of that all along the rails, then block sand; if you do not apply the coat and start to sand; you ll see that you are weaken the rail edge (less fiberglass than resin) or/and channel if you block more to the middle.
Don't use a high speed grinder on rail laps.
I ended up sanding out that ridge and it went well. But i now inherited two more problems. My fin boxes are all good, but one of them (proboxes) was not pressed all the way down on one tab. It is slightly uneven, only by a degree or two. What should i do? Also when i sanded i have some areas where i can see the weave in the light fairly easily. I put my fingers on it and it feels like it has resin in it, but i am not sure if this is considered a burn through or what. The cloth is intact and it has a feeling of resin on it. I am wonderig what to do about it. Just mix up some sanding reain and use it as a gloss coat or what… I have no styrene so im kinda lost.
Any help appretiated

ProBoxes are to be installed after your hotcoat…hmmmm. What to do about the uneven box? You have to grind that down flush with the bottom regardless of how far it’s sticking up. As long as the plastic area over the grub screws is not sanded off you can get away with it. If the cant is off you can pop in a different insert to compensate.
Sounds like you have burn throughs, need to seal them up. Either gloss/hotcoat or we’re working on a wipe-on clearcoat to seal boards with less weight and time.
Regardless of the issues you’re experiencing (we ALL do) you’ll be stoked when you get that board in the water soon!

what i mean by the box sticking up is that it was instered into the foam unevenly. There was a slight high spot in the fiberglass on my board, right where one of the tabs of the finbox was. Making one side too low, and the other too high. I am thinging just re-rout the box out and then glassin a new one. I am also wondering, what type of tints or pigments can i use in SunCure UV Laminating resin? i left it clear and it looks terrible. ANy IDeas?

Go look at some boards and see what you like. Don’t forget the catalyst. Post some pictures of your progress.
I ended up routing out the old boxes like a boss. I an just going to order two new ones and resett the boxes. I wuould post pictures but i actually dont know how,
