Pitted Cement Coping

My pool plaster, tile and coping was redone in 2008

I converted my pool to salt in 2015

Now some of my coping near the skimmers, jets and overflow are pitting (as seen in the photo below)

It is both horizontal and vertical surfaces.

Is there any good solution that will not look like a repair has been done? I am concerned if I use Quikrete patch or sanded grout the colors wont match or blend well and the coping will look spotty like a cheetah (all the repairs will be spots).
While I am no expert, I feel like my plaster, tile and decking should last another 3-5 years (maybe longer) so I don't want the situation to deteriorate and this becomes the weakest link in needing to redo my pool.

I've also read about using a sealer but people complain it makes things slippery and gives things a 'wet' appearance - so if I did this, I'd need to do all the coping, right?

Why is this happening (the pitting)? Am I doing something wrong?

Appreciate any thoughts or advice

Do a search on "concrete pitting" and you will find lots of sites explaining it.

The only thing you did wrong was selecting poured concrete for your coping. Concrete pits and crumbles over time. The problems are created when the concrete is mixed and poured and don't show for years after.
 
Allen,

What is the best solution for my problem?

1) Spot patch
2) Minor replacement of bad pieces
3) Wait until I redp the entire pool and decking. However, I am not clear on how long my 2008 plaster job will last. Overall is seems good. But I have a few issues. I noticed some re bar appearing in a spot and the plaster seams to be more porous (small dirt particles get trapped/baked into it)

What are your thoughts?
 
I think the best solution to your problem is deal with the coping when you renovate the pool.

I don't think any patching or replacement will buy you any time.

At 15 years your plaster is getting towards the end of its like. You can try and get a few more years out of it but I think it is best to do it on your time frame and not when it becomes an emergency due to a leak. I would begin talking to companies you would use.
