Seeking some hive wisdom, please. Moving into a 23-year old house with a sweet 3 1/2 car garage. Concrete is in remarkably good shape with no visible oil stains. (Man, I should get what those people drove!)

Primarily aesthetic - I won't be doing much car work. In Longmont, Colorado, so minimal rain, no road salt, but magnesium chloride in winter.

Floor is 725 sq ft plus perimeter footing wall 14" high, and half has a ledge 3" wide. Total 1,025 sq ft. Professionals say $5-6 per sq ft, which is way more than my budget, so I'll do it myself.

Painted a smaller garage 16 years ago. I understand the need to thoroughly clean and degrease, etch well with Muriatic Acid, and rinse that well. What else?

Someone suggested an ammonia rinse to neutralize the acid?
Thinking of Behr one-part epoxy, as sold by Home Depot. Maybe use their primer, too.

It's 5-6 days of labor, so willing to spend more for a better product - any recommendations?

What's best for anti-slip?

Any websites with great info on how to do this correctly, easily, safely, quickly, and cheaply?
I plan to put linoleum tiles under tires and expect to have to repaint the tire paths every three years.

Thanks in advance for the help!

My first garage I did rustbullet and it was really good.  This is from the same company and their new equivalent.

I did polyurea in the new garage and it was about $2/sq ft DIY.  The trualloy will be $1 / sq ft DIY.  It's likely higher quality material than most contractors are offering,  If I were doing the job, I'd want $5 / sq ft too because it is real work.  It is definitely worth it though.  
 

New garage.  If you want red white and black flake, I still have a lot.

I did my 2.5 garage when I purchased my home about 3 years ago. after a ton of research I decided on the Rocksolid kit with recoat primer

some tips:

prep is key, if your concrete is sealed which it most likely is you must use the recoat primer or grind it off. do the water test to see if its sealed.  clean it well, if its sealed acid is not needed.

buy/use double of the recommended amount coating
