Yeah I bought the sample pot of Blue Velvet. Only used it once but still looks great and beads well and its been on since the 13th Aug.Try : Sample size detailing products
I got a sample size pot from there of Dodo Juice Purple Haze and it's done my GTV 3 times over with half a pot left still. 5 washes after the last application and it's still going strong (good stuff!) looks awesome too
