My RV roof is a mess. I have removed all the vent covers and am trying to remove all the previous caulking and/or sealant. I bought some RV Flexible Sealant made by Pro Flex before I read all the information. I haven't found a video that covers complete preparation in detail. I have removed old inserts and and putting in new inserts in my trim.
1. If you have a suggestion on what to use to get all the old off easier I would like to know that. Or do I have to get most of it off but not all?
2. What products do I need for compatibility with Pro Flex and Rubber Roof?
