thanks for all your time and the links. I like the foam gun technique the best but not sure clearly how this works do I still need to keep rinsing my sponge when washing?
The foam gun is nice. I don't have one but If I understand it correctly you still need to use your sponge, mit, etc after the car is presoaked with foam. The foaming will just help get the dirt up from the paint with less action.
as for the waxing I think I'm to afraid to go near that. I think I would make more swirls with wax. I defintelty think I would require a buffer machine? the truck is to big to tackle by hand. Any brand you can recommend? for buffers
I agree that waxing/washing the Acadia is a chore. I don't do waxes on every wash.

I was more like wvery 2-3 months. Personally I prefer to do it by hand. If done properly your waxing shuold not add swirls. Try to use a quality applicator and maybe a liquid wax that is easy to remove. I use NXT 2.0 liquid. It comes with applicator and is not a bear to remove like some other waxes I tried before. If money is not an issue go for the buffer machine. I don't like to use one as I give up control to wax on the edges near trim and end up applying too much wax between crevices, trim, etc. With my hands I wax better. Now for removing swirls and polishing on the Acadia definently get a polisher like a Porter Cable (I am not sure why the one you linked is so pricey) or a G110 from Meguiar's. Make sure it is dual action though. If you go this route expect to spend about 200-250 US dlls for machine + pads
Also do you recommend me buying a bright light to work under as my garage is a bit dark
thanks
Sure. I work outside but when I am doing full details on my cars I end up spending sometime after it gets dark in the garage. A working light is very handy.
