Well i gave it a go tonight. Its a black Supra so *everything* tends to show. I got 1 bottle of each - one handglaze for waxing it after and one finess-it to cut the top layer off which has 9 years of marks, spots and crud on it.
I must say, i'm impressed. I didn't get the chance to do much because i only got home at 7.30 and it was almost pitch black by 8.30 and i had to clean it first. I wasn't sure how hard to go at first, so i took it lightly and it didn't do much. So i put on my brave trousers and went at it with a bit more vigour and sure enough i could see it taking a light topcoating off but what was being revealed underneath was fantastic. I'm going to get up at 6am and spend a few hours on it before work.
Anyway, its still gonna be covered in the more lighter scratches but i think once its done and then thickly waxed it will look the dogs tits.
Photos tomorrow......
