I bought a floor coating for my garage (Ucoat-it). As part of cleaning the floor, the instructions said to mix muriatic acid and water to clean the concrete. I cannot find this anywhere. the instructions also say not to use a concrete etch, which is what people keep telling me to use. Any ideas? Know of a good substitute?

This website recommends TSP, which is probably found near painting supplies. (It's often used to clean and prepare walls for painting; I believe it lightly etches the surface to encourage good adhesion of the new paint.)
Take a look at the site anyway. It strongly disuades DIY-ers from using muriatic acid, which is a highly toxic chemical, and provides some other solutions. But it also provides guidelines for its use if you do decide to use it.
Second link is for a product called AquaMix, which is touted as an alternative to muriatic acid.
Good luck!

As others have noted, you should be able to find muratic acid at a paint store, hardware store, or any place that sells pool chemicals. A concrete specialty store will certainly have it.
Muratic acid is really the only product to use for this job. There are substitutes for other masonry cleaning applications, either detergents or phosphoric acid products. Neither will give you good results for a pre-paint etch.
Do be careful, read the directions on the bottle of muratic acid and follow perfectly. It is nasty, but you can do it.
Do not mix anything with the acid other than water. Adding soap or detergent as has been suggested will reduce the effectiveness of the acid. Also, you will not on the bottle that muratic acid is hydrochloric acid, not sulfuric acid.

Muriatic acid is usually found at a hardware store. We also found it at a pool supply store. We used it to prep our floor. However there were areas that didn't adhere well so take your time on that step. (add dish detergent to keep the fumes down)

Muriatic acid is extremely dangerous and needs to be handled very carefully. Before you do anything, go to the swimming pool page at http://appliancequickfix.com/ and find
out about it, before you hurt yourself or others. It can be found at pool stores and hardware stores almost anywhere.

Try a pool maintenance/chemical sales company and / or a building supply company which specializes in concrete, brick, block, etc.

Look in pool cleaning supplies. Its used to treat swimming pools. Also, its a not-as-strong sulfuric acid. Different name, same chemical.
