not too difficult... but, i did goof the first time around...
so, i followed everyone's suggestion using the hair dryer to warm it up & peel it off. and, indeed, it came right off- clean. there was very little or negligible scuffing to edges of the pad itself from me using my finger nails to peel it off- as u can see in the pix. so, i just re-applied the same pad back on better the 2nd time...
i suggest doing the top section first, and then doing the bottom one. position the top edge first, then gradually press down from the top to the bottom to smooth out/ remove the air to make it stick on. keep a hair dryer handy just in case u make a mistake, and you can start over easily... no big deal.
if u really want to be anal, u can even cut around the wax paper before u peel it off to gauge the location where u want to place it. but, i was too lazy to do that.
also, when u reheat the pad with the hair dryer, keep the dryer a couple inches off the pad, and remember to use quick short motions over the pad- so as not to overheat any one area. this way it gradually heats up evenly and won't damage the pad.
it's pretty easy and kinda fun too.. share some pix when u r done.
