I have a black toyota celica and the sprinklers were spraying my car every morning and after washing it im finding that they dont come off easily. My friend took my car into a detailing shop and actually got the marks off, had the sprinklers redirected and everything was fine. well, the sprinklers are spraying it again and i dont want to ask for another favor so what is a good wax that will buff it out? I also just want to wax my car in general. and I want to know if its worth buying those car washing kits with the hose hookups that only have like a 3-time use thing. Thank you, all suggestions appreciated.
