Don't know why I did it but I've learnt my lesson. My immaculate BG now has a faint scratch on the front wing after they cleaned it. What's the best thing get rid of it ?
Also, going to use the Hydro2 stuff today - I spray it on and hose it off ? Then dry.
Cheers
Can't help regarding the scratch without pictures really, though I doubt its too deep if it happened through washing, unless they smacked a pressure washer into it or something!
Re-Hydr02. After you have washed the car and rinsed thouroughly, leave it wet, spray on panel at a time, leave for 20 seconds or so and then spray off, it will almost foam when you it it with the water, keep spraying until it stops, then spray a little more! M,e sure it's 100% removed. After you have done the whole car, use the open hose method to get it dry, then dab with a microfibre.
