I waxed my 01 dark green gs 430 with nxt gen tech wax and loved it!
Went on & came off super easy.
I decided to try the spray on version of tech wax. I did not like. It was way harder to remove and I found it messy to spray on.
I called meguiars and told them and they offered to send me(FREE!) any product of thiers with similar price. And, I didn't have to send back spray wax,I opted for the tech wash.
Three days later UPS showed up and it was the wash & THEY SENT ME A FREE WASH MITT TOO>
GREAT CUSTOMER SERVICE. I will buy their products again.
