deck dent filling

It's called, "useless endeavor".

All I see in the picture is a closeup of a painted surface, with a couple hairs. Dents in wood are usually steamed, not filled, but for a deck isn't this a little anal?

Sorry about the lack of detail. As a take a picture further away, I think you may have been right about being too anal about filling the dent on the deck surface. Here is another picture of the deck when I took the picture further away

What is your objective here? Your desired outcome?

Deck surface material?

Are you using the word "dent" where you really mean "depression" or puddle?

In the second photo I see what appears to be a reflection that indicates a water puddle?

Are you trying to get rid of the puddling?

fyi home repair isn't physics, comp-sci or EE...it's barely CE or ME any of the time.

got any practically inclined co-workers who could give you some advice?
