The side strips are available from our gracious forum host...FOOSBALL.COM !!! They are $13.00 per strip, either the white ones, or the new clear ones. I have replaced them on 2 tables so far (old white ones replaced by new clear ones). The ones I took off were still good, but wanted the new ones to help keep the tables current. That is not always necessary for everyone. The table will play just fine with the white ones.
The hardest (and most time consuming) part of replacing the side strips is removing the old adhesive. The whole process took me about 30 minutes (but I had everything I needed on hand, and knew what the process was ahead of time). I removed the adhesive (essentially) by hand, or fingers more precisely. Just rubbing and pulling and picking until it was all removed. I would NOT recommend using a razor blade or some other kind of scraper, as this could (and probably would, trust me on this one) scar the table surface.
Then clean the surface and inner table sides with rubbing alcohol. It removes all the grime, tiny bits of residual adhesive, and evaporates leaving no film on the surface. I used a lint free towel with the rubbing alcohol, but a paper towel should do fine. Then the new ones go down without a hitch!
Just decide whether you want to spend 13 bucks for one white strip, 26 bucks for 2 clear strips, try to re-glue the existing one down. I can't help with the re-gluing part, but maybe someone else on the forum has done this before.
Good luck!
