when was there a new formula released? the bottle looks like all the rest of the OPC bottles I have seen.
A few weeks ago. Here's the thread: http://www.detailingbliss.com/forum...product-improvements-evolution-revolution.htm The new formula should have the sticker similar to when the new ONR came out.
The new formula is like 20 or 30% more concentrated. Nothing different besides that. It makes it stronger when its undiluted.
