I had on my one year old hood stripes and spots on the brushed stainless steel. Chromol very thinly and it looks great, without streaks. Happened very quickly, smells not practical. The care product leaves an oily film, which also fingerprints are barely visible. The mailbox was treated equally and the stainless steel sink and the oven from the outside ... great stuff and 50ml rich in a normal household long.
