Great to hear MDR can be let to dwell on the surface for 20 minutes. That's really awesome, try that with some other acid soap/cleaner haha, you'll be in for a repair. I'm guessing that, since it's a gel, it won't dry out as easily? What's OPT's vision on applying MDR in the sun?
Also, the MSDS states that MDR has a pH of 2.65. So sounds like MDR has a lot of power, just needs some time, which is avsolutely no bad thing.
Gosh, I'm so excited for OPT-products right now 😀. I get the feeling, that, the combination of PowerClean, Ferrex, and MDR is the power-combo for decontamination one needs. Get rid of that freaking clay, induce minimal marring to the car.
