I made a 4, 1-1/2' PVC pipe wide box and it is really sticky. I hop onto it and stop fairly quickly is there some wax I can buy to make it slide better?
Are your edges sharp? PVC slides really smooth and usually doesn't require any kind of wax, but if your edges are even borderline sharp, they will catch on the PVC and bring you to a stop quickly.
search on youtube how to make skate wax and make some. thats what i used when my rail was'nt siding as well as i wanted and it worked but only use a bit at a time because it slides alot, i would recommend sliding the block of wax along the rail once at first and whenever it gets a bit less sliddy repeat
