Ken's got that idea, but glaze goes last it's just a wet looking layer and fill in the missed sopt.
Get some spray detail anyone will do. do a 1ft by 1ft area at a time roughly. Spay the clay make sure its nice and soft.
Make sure you have 2-4 microfiber cloths.
Spray the surface and the glide the clay over top. once done gliding then wipe with one cloth. once done a panel use a second cloth to wipe it down again.
do the same for the next part fo the car too.
Excpet, spray the clay once again and mold it around untill there is an equal amount of clean clay showing to the surface of the paint.
The whole purpose of the clay is to take off debris and fallout from the railcars.
White cars are the worst for showing fallout.
the once done the clay bar you can take some quick wax. Weather it be in spray form or bottle form and apply to the surface let haze up and wipe off. do not let set for too long it will only get harder to wipe off and easier to cause clearcoat scratchs. Best results is with a orbital when wiping off.
Good luck buddy don't get any of it on the plastic panels and you should be golden or shinny liqude grey lol.
You got my number if you need something.
