I have a half bottle of crystal mist left and thought about dilluting it with water. Since im ready to buy the 64oz of crystal mist refill, i said to myself why not. So I filled it with water and used it on my freshly washed car. I didn't see any difference on appearance. The paint still felt slick and looks good. The dilluted crystal mist was easier to use since it's not as thick as before. It now sprays a very fine mist. I did notice though a little streak on my hood but that could be just i didn't buff it properly. I wiped it with a MF towel once again and removed the streak with ease.
