I used a foam applicator with MDR, applied to the paint, let it sit for a 2-3 minutes, washed off. Did the bag test and found no contamination.
I tried a similar approach on my hood because of contamination, the hood being coated with CarPro CQuartz, leaving the MDR on for about 20 mins as I couldn't get the contaminated to leave. I washed the hood to remove the MDR and found the coating to be DEAD. I was shocked to see this. Have you heard of this before? I thought MDR even with long dwell times was coating friendly.
