Why are you upset that antags are using game mechanics such as maint and space lube to their advantage? At least they're putting more thought into it than going stealing a taser. Tasers are honestly worst, in a 1xY corridor, you're likely to get fucked by them.
Simplest solution? Don't be an idiot. After a while, space lubed tiles should start sticking out, if they don't just stop running after the guy once they pull out a squirt bottle or beaker.
Besides, it's not like only antags can use them. Being chased by a duel esworder? Space lube.
Wizard? Space Lube. Nuke Ops? Space Lube.
Sure, it may seem power-gamey, but there's not much you can do, a lot of the mechanics in the game are power-gamey, and hate to say it, but without them, it'd hardly be fun.
