Lots and lots of work. I suggest bite the bullit and buy a PC, the time saved makes up for the money spent. To answer your question you can use scratch-x or something like IP or #80. Use a MF pad and apply the product on a 1X1 foot area until the product is gone then a final wipe of the area and inspect the area. Repeat as necessary until you are satisfied with the results. Be prepared to take a whole day or more to do this. Then top with your favorite wax.
