Op it takes a few times but u will get it down. Practice on a crappy car if u have one before going at it with your 40k camaro. Have your water tested see if thats part of the problem. Drying a car i use a electric leaf blower it removes 95% of the water then i go over it quickly with a microfiber drying towel. After that quick detail spray and your done car should look brand new. Good luck
