Review (1/5): cool temperatures, inside and outside
No matter how I use it it streaks. Tried thin, sparse spray. Tried heavier and full buffing until gone. Tried warm temperatures, cool temperatures, inside and outside. This is over Opti-coat pro. Using good, name brand thick micro fiber towels, one for one one for dry. Nothing seems to work to keep from streaking.
After on, it is hydrophobic, just does not add anything to the looks or shine.
