Ding Repair Suggestions (with pics)

[across07]

Hey all, I've been a lurker for awhile, decided to finally join. Looking for a litttle help and clarification here. I started surfing a couple months ago and am about to attempt my first ding repair on a board I bought used. I've looked at a number of the old posts on this forum about it, and watched quite a few youtube videos, but I've got a few questions just to make sure I'm on the right track. I'm sure all of these things are pretty basic/standard repairs, but I'm being extra cautious since I'm a first timer. Here are a number of pictures of the dings I need to repair (or think I need to). Hopefully the pictures turned out, I figured it would help you to give me advice, and perhaps other people with similar problems can use this thread in the future.



To give you an idea of the size of this, it runs close to 5 inches along the bottom of the board. Perhaps as wide as a fingernail. The guy I bought it from said it is from his roomate cinching the board down too tight on a roof rack. I believe it's watertight, but the glass is starting to discolor so I figured it was time to repair. How would you suggest I go about a repair so long? Should I take a razor blade and cut out the whole length of the discolored glass? Or just sand it very good?



This is a standard spider crack, this one again is beginning to discolor some and definitely needs repairing. Again I guess my question is should I cut out all the glass around the crack, then fill?



This is perhaps a little delamination? I'm not sure if I'm classifying that correctly. It's not really a ding, just a small area on the rail where you can see the fiberglass cloth. Same question again, do I want to cut out the problem area, or just sand it down?

These next two pictures are of small issues that I'm not sure need repairing or not. Advice on whether or not to repair would be appreciated



This is just a small hairline crack that runs 1 1/2 inches or so from the fin box. I've read about doing the fingernail test on small cracks like that. My nail does catch this crack, and therefore I'm wondering if I should repair it? Anything I need to be aware of doing a repair by the fin box?



I'm not sure if this picture is clear, but it is a standard round pressure ding with a slight circular crack running around part of the edge. My nail does catch this circular crack, does this mean I should repair? Would I want to cut out around the whole pressure ding, or just try to sand out the crack, or something altogether different?

Those are the 5 dings I am wondering about. I've got Suncure, and also got a Ding-All repair kit for Christmas, so I was thinking I would use the Ding-All since I've read that usually you will get a longer lasting repair job doing it that way? Sorry for the long post, hopefully you all can help a beginner out. I've already learned a lot from reading these forums. Thanks

It's a bit hard to tell, but I dont think I'd bother repairing any of them - they look like very minor cracks in the glass, rather than a ding. I certainly wouldnt start removing bits or sanding them down - you'll just make the problem worse.
The only one I'd worry about would be the crack by the fin box as it looks like the fin box has been pushed in a mm or so and that crack might not be 100% waterproof. Personally, I'd just use a very small amount of suncure in there and then sand it down so its as flat as possible.

No dramas - every one of my boards is a whole lot more battered than that

Firstly welcome to surfing waves!

You can discard 1,2 & 5, they all look watertight.

Number 3 is fine (it is not delamination by the way, just stress) but if you want to tidy it up then give it a light sand, pick away the resin flakes and spread over a minimal amount of polyester resin to re-saturate any cloth that might be exposed.

Number 4 looks nastier. Push down hard next to the crack with your fingernail to see if the crack had penetrated (split) the laminate. If it gives, then heavily sand around the crack and about 1cm either side to expose the fibreglass and apply a patch from your ding repair kit with just shy of an inch overlap either side.


Good luck!

Thanks for the welcome. I was taking a little bit closer look at the board today and noticed something that caused me a bit of worry, although maybe it shouldn't. I was looking at the area of the board where 2 and 3 are. 2 and 3 are right next to each other, 2 is on the bottom of the board, and 3 is on the rail. You can vaguely make that out looking at picture 2. There is definitely some faint discoloring, I wouldn't call it major by any means, but it's there. I also noticed for the first time that the area looks like it has swollen slightly. You can only notice it when you look along the bottom of the board. Is this a sign that some water has seeped in? If so, should I go about the repair in that area differently?
