Thanks to Deanski, I now have some PB polishes in my possession. Can someone give me a brief primer on using them before I go outside and tackle my father's Navigator?
BTW, the application method will be (probably) by hand.
EX-P is really easy to use by PC; it will spread a long way. I apply it by hand to the door handles, rocker panels, under the spoiler...and it's a little tougher to apply by hand. It feels thicker, and sometimes the applicator pad will roll up or fall to the ground. Just make sure you have a couple clean applicators on hand for EX-P. I'd recommend doing as much of the car as possible with the PC.
I haven't tried any of the Poorboys polishes, so I can't be of any help there.
If the Navigator is in average shape, probably go SSR2>Pro Polish>EX-P. Just follow the directions on the bottles and you are good to go. If the bottles you have don't have directions, you can get them on www.poorboysworld.com
