If any of you need to remove some tar from your paint work give me a shout. Getting some special cleaning crap from a contractor this week due to getting some on my car. I will be at the meet next sunday anf fcs if you want a quick clean down.
Petrol does the job brilliantly, I've used it for years without an issue. Failing that Autosmart Tardis is better but costs a bit more. I'd personally be wary of anything that a contractor gave me, god knows what it will do to the paint work.
