All great advice above, do the sheet rinse (no sprayer), use a blower to chase the spots, and finish with a detail spray mist and micro fiber drying towel. Follow that and you will have a spot free Monte that shines.

Here is a pix of mine freshly washed with hard water in the sun Saturday afternoon.

Welcome to the world of having a black car where you see any little inperfection!

Another thing you could consider is rinseless wash, get yourself 10-12 quality plush microfibers and a quality waffle weave drying towel,

mix up rinseless wash, put all the microfibers into solution, do one to 2 panels per microfiber (real diry rinse car off first to get rid of built up dirt ect) once done with panel bry with waffle weave

hi i would try a product call beyond clay it is made by sirf city garage it removes hard water spots i use it all the time

X2 works well & much easier than a clay bar. I have used it on a foam pad with my porter cable. Clean and smooth paint the easy way.

[QUOTE=03SSLE;545858]You can try using a quick detailer spray while the surface is still wet. Spray some on then wipe with a microfiber towel.

Agreed!! and always wipe the car down while still wet. Do not let the surface get hot.

Water softener ;)
