Nice job on the test U2.

How about a... Test, Part 2. Where you test it on a super textured board deck. Many beach or mast dings happen at the beach to the top of the board.


Ok, I think I have the same dumpster board , that has the deck like that.

This test came about, when on another thread it was posed if tape could be used to seal off unused fin boxes, OR provide a temp repair on a broken box.

From this “test” its still a no harm no foul presentation to seal off unused boxes. My preference is use the blank, which should be in your spares box.

If the board is damaged (as broken box )where the inner core is either exposed or the potential is exposed, I would not risk water inside and use tape.

Sealing off unused finboxes (that aren't damaged) just for better, smoother water flow ??

Can't you just about use any waterproof sticky tape for that?

In the 80's in the gorge and around the world, people sailing longboards in 20+ knot wind were taking the centerboards out and covering the big slot on the bottom with duct tape. That seemed to work well enough for quite a while Smile

Yes , but not my idea , which is use a fin box blank.

Tape is seldom described as water proof, water resistant , yes.
Agree duck tape works well enough for quite a while. Define well enough and quite a while ?

I put a 1/4” diameter puncture in the bottom of my board near the back footstrap this weekend while loading up for a session. Since I knew epoxy would not cure in time, I just squirted a little super glue in the ding and then covered with a small square of Tyvec tape (the stuff used to seal vapor barrier on the exterior of houses).

I was skeptecial on whether or not it would work, but after an 1-1/2 hour session with constant immersion, the tape held fine with no signs of peeling up. I don’t think it would work on textured non-skid or around sharp contours, but for small dings on flat smooth surfaces, the Tyvec tape seemed to do well.

Aluminum tape can last the board's lifetime.
They make suncure epoxy for a reason.

Tab on image, X on the top right to eliminate the credit card BS.

G is Gorilla Super glue, L. Is locktite all purpose glue, luv this works on lots of stuff. This piece of EPS is 2lb , at least .5 more dense than almost all BOARD insides are, which is anywhere from 1, to 1.5.
Approximately 4 hours , almost as bad as Alien blood, Alien from the movie.

never tried it, but would trust this dingall over experiments with glue ...
as someone said - SolarEZ or others with UV activation too
that one is messy to carry about, but does dry real fast

ding all seems to have sun cure products as well

here they are saying 15 minutes to cure before going on the water ...

My test with super glue was to show it’s not a good repair.

Yes, you guys are correct. Upon further investigation, it looks like using superglue is not a good idea, especially if there’s risk of it contacting the EPS foam core. The ding on my board was not through to the EPS, so I got away lucky (I actually did a few small test drops first to see if it would be ok and nothing melted...). It was a rush job on my backup “junker” board, so I wasn’t too concerned - but I agree, Superglue not recommended for internal board repairs.

I think I can still vouch for the Tyvec tape though. It seemed to hold up fine with no adverse effects. Of course, as with any quickie patch job, you do it at your own risk. I would (and did) probably think twice about using any tape, glue, or quick set epoxy to repair a board I really cared about. Laminating epoxy and glass/carbon is certainly the best and longest lasting repair method.
