i have used chemicals guys stuff there pinacalada and if you spray it in concentrated form (one spray) will last several weeks......i havent used the leather smell but was super happy with the pinacalada.......then you can play with the ratios to find something that is stronger or weaker, i mix up several different variations of strengths because some clients like softer smells and some like bold long lasting smells.....just mix it and find whats right for you and your clients
