BestTrack joint prep

I got a used 42" single lane Best Track 5 years ago. I have groomed it 3 times. The last time was a very extensive process. Recommendations from other folks said to start with 100-150 grit sand paper. I thought that was way too aggressive but as it turned out, it what was needed. I stepped through the different grits finishing with a 2500 grit (wet sanding) and then used a polish/wax paste. I first groomed all the ends of each section then assembled two sections at a time and used a block with sandpaper wrapped around it to go over the entire track. The joints tend to have a rise so I worked them until it was level. When working joints with sections assembled, ensure sections are PERFECTLY aligned straight, otherwise you will have a flaw, especially on the rail. I also marked the ends of each section so the track assembly remains in the order that it was groomed. It was a ton of work but it made a huge difference and it stopped chewing up my wheels. With a brand new track, I suspect that only the joints/ends need attention. I've seen organizations tout they have a new track but failed to groom it and the results were cars jumping the track and or tearing up the wheels big time. Since you will be setting up and tearing down often, I would build some kind of custom foam fitted protectors for each end of each section. As you know, just a minor bump on the ends when moving/storing track can ruin your day.
