I bought a PC about 3 weeks ago and 3M 3 step compounds, Mothers cleaner wax, and some of the stuff to get the water spots off the windows then a ton of pads. a little over $300 in stuff.
I didnt use the products on my mustang yet, i used them on my truck to start with, the truck is a 2001 blue dodge ram with 10" of lift so i was on the ladder a lot, lol. the truck was in bad shape, its outside all day every day, lots of eched in water spots on body and paint, chrome bumpers are dull.
So, i went to town, clay bar, #1, #2, then #3 and then wax, to say the least the truck looks amazing, i didnt get all the scratched and swirls out but about %90 and %100 of the water spots are gone , the surface feels like smooth marble. I hit all the chrome with mother mag polish and i got a chuby with the results of the "look new" bumpers. did the windows with the widow cutter, had to do it a good bit but in the long run almost every water spot is now gone. i wish i did this a long time ago.
My mustang is up next, i had to order new pads today, the truck did a number on these, i really didnt want to have the old pads on the mustang.
