Easy Pro Update

A while back I posted an initial review of the JFJ Easy Pro disc polishing system. I’ve now had this unit for over a year and have some updates.

My first observation is that I’m probably not using the proper amount of polishing fluid. The first time around the white buffing compound got used up faster than the blue. After my refill purchase I think I have them running down at about the same rate by reducing the amount of white and increasing the amount of blue that I use for each session. I don’t know if they’re supposed to run out at about the same time, but I would think so.

My second observation is that if I polish a number of discs at the same time (which I usually do, since it doesn’t make sense to get the pads wet just for one or two discs) then the machine heats up. As it gets hotter, it seems to “fuse” the blue polishing compound to the pad. That means that when I try to put additional fluid on it is fluid on top of gelled fluid instead of the buffing pad. Periodically I take a pocket knife and scrape the congealed blue fluid off of the buffing bad and that seems to help. I decided to start doing this when the first blue pad eventually wore out, and I saw how much better a new pad worked. By cleaning off the blue build-up the blue pad does a better job of polishing. The white pad does not seem to suffer from this same issue.

As expected, I use about two white pads for every blue pad. The white compound is a buffing compound, meaning it’s responsible for removing material from the disc to get scratches out. The blue compound is a polishing compound which means it uses less friction, and therefore does not wear out as fast. Instead of ordering new pads (and fluid) from the manufacturer or Amazon I found a vendor on eBay that sells the materials much cheaper. I bought pads in bulk (10 pads at a time) last time to get a better “per pad” price. If you have a lot of discs, I suggest you consider doing the same.

I now have close to 3,000 discs in my collection, and I’m pleased to say that the average purchase price has gone down since I know I can pick up a scratched or scuffed disc from the bargain bins and come home and clean it up so that it plays just like new.

There have been a few exceptions. For example, one copy of a Led Zeppelin disc I brought home would not rip no matter how clean the surface looked. Ultimately I found out the problem by holding the disc up to the light. I noticed the light shining through the disc in a couple of places, meaning the data was completely gone in those areas. It affected two of the songs, unfortunately, so that disc had to go away. Now I check my used discs for this sort of defect before I buy them. No amount of buffing or polishing will restore a defective disc.

I also purchased a J Geils Band Greatest Hits disc that was deeply scratched – enough so that I used sand paper on the disc as the initial treatment. I was able to get most of the scratches out on the bottom, but then I noticed that the top was equally scratched. Of course I can’t polish the upper surface of the disc. I’ll probably keep my eyes out for another copy of this disc that is in better shape and pass my current one on to the library.
