I've been using ONR for about 2 years now and I remember when it went to the blue color. I recently received 2 gallons in that appear to have some changes. The blue is a deeper shade and the smell is different. I can't quite place the smell but I've smelled it before. I'm thinking it was the smell used in Poorboys Spray and wipe or Spray and gloss, I can't rememer which. The ONR seems to work as great as it always has. Although I wasn't a fan of the old smell, I'm not sure I like this anymore.
