I used Jasco from a spray can on a Schwinn Sierra a couple weeks ago and the paint wrinkled up within about 30 seconds and I had the bike mostly stripped in 10 minutes or less. It was amazing!

The only parts it didn't touch were the places still covered by the decals -- I had to scrape them off and then respray those spots.

One note, my Sierra was entirely chrome under the paint. But I don't see how that would effect performance...
