First wash and clean with good brush (I prefer a hand brush for the caulk), then apply Acetone applied with a rag over caulk and all areas where tape will come in contact.
It also helps to carefully remove areas with mounds or thick caulk (using a razor). I found that covering high caulked areas with the tape makes the tape wrinkle and cause air bubbles. I just completed two roofs and I am happy with the results.

Take my posts for what they are, opinions based on my own experiences.
What Steve said X2. If doing a large amount, get a small wall paper roller to work the bubbles out. Keep your knife handy, as slicing a small hole for air to be worked out of bubbles/wrinkles is ok to do. It seals back up well.
Best of luck,
great product. Once it is on, it is on. work slowly and if doing front to rear seam try to do it by rolling out about 6 inchs at a time. I messed up and did sections on one side. more cosmetic than anything else. the side I did in one piece looks much better. clean the area completely. I sealed every seam I could find on roof.

Acetone will not harm the roof. If you are realy worried about it, they make a cleaner and a primer for the Eterna-Bond. I did my roof with and with out the primer and cleaner. I used Acetone always and a heat gun and flexable putty knife that I rounded the edges off so it would not dig into the roof. I also used plane old paint thinner to remove the byutal rubber calk under each roof penatration. I lifted everything except the A/C units and cleaned and resealed everything. I did use the Acetone imediatly after the Paint Thinner to prevent any damage. It took me two seasons to finish everything but I was in no rush to finish. While I had the roof vento out I took pictures of and tried to trace all of the wiring in the openings I exposed and replaced the Ventline piece of******in the bathroom with a new Max-Airr in the bathroom and repainted all of the parts for the Fantastic fan in the living/galley area and replaced the Reefer and sewage vents. While I had the reefer vent open I fished some #16 wire to power two muffin fans to help the reefer in hot weather. Good luck with your project and take your time you will be happier that way when it is done right the first time. Ed
