See pictures below.
Can I just clean it and put some leveling compound on this front half and then epoxy it? Back half was added much later btw.
For what I would expect out of your request (a good long term fix), the answer is no.
That looks to be old concrete (relatively speaking) with freeze/thaw cycles, salt/brine from your location...
John has the best answer for best results. Anything else will be like a coat of Thompson's water seal <<SPIT>> on a wooden deck... It won't last long...
A small project like that is really not difficult as a DIY if you plan properly. The key to any and all concrete placement is reinforcement and control joints. I am not talking about wire mesh either.... That is even more useless than Thompson's water seal....
