You'll see the results of using Peel Away on Rhapsody at this link:
http://j30rhapsody348.blogspot.com/p/rhapsody-bottom-redo.html I used the paper for most of the application, as you want to keep the chemical moist and it is cleaner when scraping. Some limited areas required additional coats of Peel Away, and I didn't consistently use paper for that. Makes a mess when scraping though. "Peeling" the paint is an advertising misnomer. You still need to get the scraper under the paper, but when the stuff works, the paint peels off very well. It still requires elbow grease.
Warm temperatures are a must with Peel Away (warmer than 60 degrees, and the warmer the better!). Due to mother nature staying cold last spring, and the launching date drawing near, I rented a tent heater when the temp outside was in the 40s and used it with a tarp cocoon with limited success.
