Working on my mom's Honda Pilot that hasn't had wax or sealant in several years. I did a two bucket wash and then used my new nanoskin fine grade mitt. I followed the directions and broke it in the glass. I used Maxi Suds II as my lube and thoroughly went over the car. Did the Baggie test and could still feel a lot of contaminants. I grabbed the mitt and did a test spot on the hood with onr as my lube. Still contaminated, so I grabbed some fine grade clay magic. Went over a small section until it was decontaminated. Went back with the baggie and could STILL feel contaminants. What the heck? It's like this all over the car. I figured I could still get heavy contaminants off with the fine grade mitt, but it might take a little longer. Any help is appreciated.
