i have already bought muriatic acid ,,, can i still use it diluted?? then rinse well ,,,is there a primer for this epoxy base coat?? Should i use 2 coats of base coat for auto shop,, then apply chips , then hardener?
Muriatic is too aggressive and can have issues with an epoxy if not fully rinsed. You do not use a primer. Only one coat is needed unless using one of the two lighter colors. For more durability, use the top coat last.
