I was doing a test for a free dash cleaning product that I received from AG. The dash had been treated with OPP 3-4 months ago. After cleaning part of the dash, I noticed how much of a difference there was between the clean area and the area that still had OPP applied to it. My question, is OPP still protecting after 3-4 months or is it just the "film" from OPP that was still remaining?
By the way, which side looks cleaner? The left side cleaned with Simple Green diluted 30:1 or the right side cleaned with EcoTouch Dash + Trim Cleaner?
