Aww Abbas, lol, I read your last 2 installments with a smile on my face. All I can say is your a trooper and have become an excellent problem solver.
It’s so hard to learn and also to do some of the things you are doing by yourself.
I am giving you great credit.
Several times I said to myself, I wish I was there to give you a hand. But you are recovering well. more smiles, sorry.
I would probably just use some rockhard water putty for those dents. Hide glue and dust may be alright, I have no experience with it. Something that sands easy and won’t make any dips in the surrounding material as you try to sand it flush. Ripples are going to be your enemy as you try to veneer it. Try to get everything as flat as possible.
I like your style :)

Figuring out how to do something you have never done is what makes a good challenge.
