I like the VCT look and am planning on doing my floor soon.
I was looking at Armstongs web-site at the VCT and ran across the SAFETY ZONE line. It is for commercial use near water other slippery surfaces. I wonder if this might be a better fit for a garage?
I e-mailed their customer service and asked if they have a VCT they reccomend for garage floors and will let you know what I hear.
Here is a link to the safety line....
