Yeah not as good as the old stuff that had methylene chloride in it. What I hated with the abrasive strippers is all the dust so I gave it a try (its not cheap either....$100/gallon up here). I'm told it works much better on aftermarket paint vs factory paint which is why it doesn't seem to be working that well on my roof. Just brush it on (one pass with the brush) and then quickly lay plastic on top. You will need multiple applications.
