Is there any point to even bothering with it in the first place if you don't have the porter cable tool?

If you don't have the PC then how do you apply the wax or polish?

 

You can get really results by hand. With a Porter Cable you can correct swirls and scratches that you wouldn't be able to do by hand.

My OD Light Polish and Optimum Polish both work really well by hand. Optimum Poli Seal is a all in one paint cleaner,polish, and protectant that works great by hand too.

I like to use foam applicators to apply polish and wax. Microfiber or terry cloth applicators absorb a lot of your product, the foam will let your product go alot further.
