I have a Whirlwind on the way with some wear around the center spinning disk. I've therefore ordered a decal to cover the wear: ebay.com link: WHIRLWIND Pinball Spinning Disc Repair Decal LICENSED
...Do I dare be lazy and put the decal (which is relatively cheap) over the original mylar, or do I go all out and replace the mylar with the risk of pulling up inserts, damaging artwork, etc.? Note: I've never replaced mylar before, but am familiar with the various techniques (freeze spray or a heat gun to remove mylar; chemically remove adhesive residue).
