For something so simple it sure is helpful when I'm detailing vehicles. I have a dedicated wash bucket for wheels and tires and with this sticker added to the bucket it guarantees that I won't use the wrong bucket when I clean my brushes for wheels and tires.

I expected it to be big enough but it was way to small. It's good for a cup but not for a bucket .

I have several buckets, I try and keep them separate. Just put these stickers on them, Wash, Rinse etc... Never get them confused again. Great addition to your supplies.
