Thanks for the detailed info.

My floors are definitely dirty and cracked. I'm going to powerwash the floor next week and if I decide to do the coating I'll rent a scrubber and use a degreaser before etching. The cracks I'll fill with an epoxy crack filler first or just go right over them and not worry too much.

I don't often bring in cars that have been out driving around a lot...in fact most of the time a car comes in and sits for a long time so I'm not super concerned about hot tire pickup but I'd like to protect against it anyway.

After I paint the walls and shelving and so forth I'll see how it looks and make a decision then I guess.
