madness!!!!!!!
i was recently reading the "ask the retail doctor" tips on http://www.properautocare.com/. i really hope you don´t follow their tips because then you´ll soon be very sorry. when i was reading through their tips i was just laughing at their complete lack of knowledge i the field of auto detailing. "This contamination can not be removed by washing, waxing and/or polishing" is what they had to say about paint contamination, bull¤¤¤t is my answer to that. my company does this on almost a daily basis with a light type of acid and get superb results and i have the car dealers to prove it.
when cleaning the cars paint no matter wether it is tar, oil or paint contamination it´s only a matter of chemistry thats it. for example:if you want to remove tar from your car you need a petrolbased solution to dissolve it. a biological solution wont dissolve tar. it´s like mixin oil and water it can´t be done. this principle applys to all cleaning wether it´s the interior or the exterior and i´m a bit surprised that they clearly don´t understand this fact.
and don´t get me started on how they use the polishing machine.
NEVER TILT THE MACHINE!!!!!!
