Did a my uncle's Black Mercedes yersterday. Used M80 for swirls removing & M21. Was kinda disapointed while wiping off the M21....streaking almost every where. Used QD to wipe of some but not all. But I guess it was kinda hot day yesterday so should have use other wax/sealant instead. This is the second time M21 have done this to me.
Do u guys know of any wax/sealant to recommend that doesn't streak on a black car, even if its a hot day...? I don't want to waste the whole day again detailing and end up with dissapointment. Ugh... Thank you kindly.
